  1. Hi Rampage,

    Followed the guide exactly, and made it through the installation.

    (I did have to use the nv_disable=1 flag, but don’t think that is related to this problem..)

    When I booted into my Clover USB afterwards, however, the disk with the Yosemite installed no longer appears, so I can’t boot into it.

    Any suggestions?

    • So you booted to the installer, formatted the disk, selected the Drive to installed to and then clicked continue and then failed to boot into the installer the 2nd time is what I am understanding. If you don’t boot to the installer the second time you are not actually installing anything.

      • OH I understand now!

        I thought I had just installed it, because at the end of Part 7 it says “when the installer is complete restart”.

        So in part 8, step 3, I saw “use the arrow keys to select the drive, etc.” and thought I’d be able to see the installed drive already in the Clover USB disk list, but not so!

        It appears to be installing now after choosing “boot to external” on the second round.


    • I’ve sorted out most questions on this, original post can be deleted.

      • Do you mean the boot0: error?
        I have looked for it in the comments and not found anything about it.

        I had the same allocation error when using aplo v2, created a new usb disk and tryed not selecting any aplo driver but then i got a boot error0.
        Also happened on another key that used to work, but then all of a sudden gpt boot error

    • Hi Rampage,

      I appreciate all your hard work on here. I’ve been having a lot of trouble getting my x79-up4 to fully boot after swapping out my 4930k for a 2697v2. The bios sees the CPU and gives me all readings from all 12 cores, but I can’t get it to boot into my osx install. Was solid with the 4930k. Do you know if getting the 2697v2 running is even possible? I’m on 10.10.4.



    • Followed everything to the “T” (Coming from MultiBeast…) so this entire process has been an EXTREMELY large learning curve. So much information, so little patience. Such cool results!

      -Ok, ran the installer but would not complete. I feel like I may have chose the incorrect system (Dual CPU) while setting up Clover initially? Yes, I tried some quick Google-searches but came out with my hands in the air 🙂

      Lenovo Yoga 700-11isk (Touch screen is actually working through the EFI interface)
      Intel (TM) m3-6Y30
      Intel HD 515
      BIOS vs. DDCN26WW(v1.10) – For what it may matter?
      Intel AC-Wireless Combo (Using ASUS AC1200 dongle, works)
      128GB M.2

      *I have partitioned the M.2 during a MultiBeast whack at it and partitioned a separate living space for Windows in Fat-32*

      Just want a cool notebook!

      • For the record, the “T” in which I followed, was this guide 🙂

        Well written! I would have personally benifitted from understanding (or maybe a side link explaining..) how to figure out which UEFI system I own.

        This was the ONLY gray area I could find, and of course that’s most likely due to the lack of knowledge (obviously) that I had going into this mess 🙂

        Thanks in advance, you’re efforts are really appreciated

      • This guide is not intended for Laptops but please check out this:

  2. I got through the install successfully, ran the initial setup and downloaded your x79 DMG.

    I got through all the steps up to the first reboot — but after rebooting I found I still could not boot without nv-disable=1.

    Now I can get to the login screen, but after entering my password the computer gets stuck on the spinning BBOD.

    My mobo is a p9x79 Pro and my Graphics is a GTX 560 SE. It seems to be a graphics problem, but I don’t know what I can do without being able to get into the OS to install some drivers or something.


    • Update:

      Was able to borrow a GTX 760 from a friend, and I booted up no problem. I guess the 560 SE has issues with Yosemite 🙁

  3. I am not clear about step 6 of Part 6: kext installation:

    “6. Copy the Kexts into that folder.”

    I’m not sure what ‘the Kexts’ are or where they come from. I assume that “that folder” refers to the /EFI/CLOVER/kexts folder described in steps 4 & 5.

    I’m trying to install 10.10 Yosemite on an x99-UD4 motherboard.

    Can you please clarify?


    • Kext go in:


    • This part was a little confusing to me also. I believe the kexts he is referring to are the “generic extensions to boot” that has a link which will download the kexts for you.

      I think it would be more clear if it just said “download the kexts here” or something. I didn’t know what generic extensions meant.

  4. Thanks for this great guide. So there is no issue with Haswell early reboot as in laptops no need to have KernelPM enabled in Clover? Also any issues with the latest Bios from Asus as far as CFG locks. One very important question is the OsxAptioFixDrv-64 driver do we use original version or V2 now in the latest Clover installers? For POST install do I still need clover config.plist with npci=0x2000 option enabled or not?

    Motherboard Z97-A CPU -i7-4790K


  5. Hi Andrew,

    I have followed the instructions and arrived to the Clover installer. At this point when I attempt to boot it hangs on the apple. Where can I enter the boot flags?


  6. Yes I have found the options and tried a multitude of variation in the boot arguments.
    When I enter “-v cpus=1 npci=0x2000 -v cpus=1 npci=0x2000 nv_disable=1” in the arguments, (I have nvidia 780 GPU)
    (I even tried each argument separately)
    I get the following text then freezes:

    OsxAptioFixDrv:Starting overrides for .IABootfiles\boot.efi
    Using relic block: no, hibernate wake: no
    efiboot loaded from device:Acpi(PNP0A030)/Pci(1D|0)/Usb(1,0)/Usb(5,0)/USB(3,0)/HD(part2, sigF342a)63….
    boot file path: .IABootFiles\boot.efi
    root device uuid is ‘7286D……………….long list of numbers…

    Any clue?

  7. Everything installed flawlessly both Pre and Post. I get this error every time I get to the desktop, The Disk You Inserted Was Not Readable by this Computer, Initialize, Ignore or Eject. I have two samsung 512 SSD drives, one for windows 8 and the other for OSX Yosemite. I have Trim Enabler, enabled. I may re-install windows 8 because I may not have installed as UEFI if that is even possible? If that is the case could that be why I get this error when I get to the desktop? The disks showing on the desktop are the OSX for the one SSD with clover and System Reserved and Untitled disk where my windows 8 is installed for the other SSD. I have the Asus Z97-A MB with Haswell i7-4970K Processor. Any help on this would be greatly appreciated. Thanks

    • I have the same MB.Did you do any other steps aside from the instructions above? I was also able to install Yosemite but needed the USB to boot. My problem though is I don’t have a network. How did you install the network?

    • I guess that your issue was regarding with the Windows’s Dynamic Disk feature. You have to go into Windows, use Disk Management to see if your Windows System disk is being a Dynamic Disk.

      If so, then for safe, first – backup that disk and keep a copy of any other important data on an external storage. After that, try and use some third-party partition software to convert that Dynamic Disk to Basic Disk. Once conversion completes, you’re ready to see if OS X is able to mount that disk properly now.

  8. I figured it out my fault. Its usually users fault 99.9% of the time. I had a drive connected that was not formatted and lost thought that I had another drive connected to the sata. Once formatted that message went away obviously!!

  9. Hello Andrew, how could I change the clover bootloader theme to
    full screen 1920 x 1080, my bootloader screen looks like 1024 x 640…thank you

  10. Hey Andrew,
    Thanks for this guide, I was having a ton of trouble with UniBeast (Banned) so I thought I’d try giving Clover a try to install 10.10. I’m installing on an Asus Z97 with a 4790k and GTX 760. I was able to follow the guide up to Part 8, I wasn’t familiar with Clover so I started the OS X install without adding the kext-dev-mode=1 boot flag. Even without any boot flags I made it to the Yosemite Install. After formatting the drive and hitting install OS X, I get stuck at “About a second remaining”.
    Am I ok to just hard reset the computer and retry the install from step 8?

    • No. You need to wait. This counter has not worked since 10.8.5. Let it do its thing. Its a Apple issue.

      • I just let it be and after 10 minutes the screen just goes black and nothing happens (I even left it like this overnight). Once this happens I can’t boot into anything with the usb drive plugged in or unplugged. I can’t get to the UEFI USB Boot screen, and I can’t even get to the BIOS screen. The screen just stays black when I turn on the computer and it stays like that. Any thoughts?

        I tried from the very beginning by reformatting the USB drive and installing clover and the Yosemite install drive. I also added the “-v kext-dev-mode=1 nv_disable=1” boot flags and the same thing happens.

        • So the system went to sleep is what you are telling me but you did not realize that it did.

          Sounds like more is going on here.

        • If the computer is going to sleep while its stuck at “About a second remaining” what should I be doing instead? I don’t see how it would go to sleep in the middle of an installation and why that would prevent me from booting up into the UEFI boot screen again after I hard restart the computer?

        • When it hangs this is normal.

          Something may be stuck in the NVRAM perhaps.

        • Was there every any more follow up on this?

          Mine is also getting to the point of initial reboot after the 7-9 minute “initial Yosemite install” and going black screen — at which time it’s supposed to reboot and we are to select the Install Yosemite from Clover menu to continue/finish the Yosemite install

          And the only way for me to get the computer booting again is disconnecting power cord, waiting 8 seconds, re-connect and boot again.

          ..but then I’m just back to step one because when I start the Yosemite Installer again it’s behaving as though it’s the first time, all over again.

        • Don’t let the computer go to sleep.

        • As a follow-up I was able to get through the entire Yosemite install and first boot-up into the desktop using the follow flags: “dart=0 kext-dev-mode=1 nv_disable=1 PCIRootUID=1 -v” At the same time I was wiggling the mouse the entire time it was stuck at About a second remaining to make sure the computer didn’t sleep (though it doesn’t make sense to me why sleep would even be enabled during an install). I can’t tell you which of these was the reason for my success. Good luck!

        • It will take up to 20 mins to get past 0 time remaining.

          Please do not use unsupported boot flags and mixing install methods as the Flags you used are incorrect and shout not be used. Your creating issues.

  11. I have tried everything in the instructions, but the the installer keeps rebooting on me. (MSI Gaming 5 + i7-4790K GPU)
    The verbose mode is moving too fast to read. Is there a log file I should be looking for? Any ideas?

  12. Hi Andrew,
    (Specs: Asus rampage V, CPU: i7-5960x)
    I’m having a problem to install osx.
    After all the steps every time I boot the usb key it hangs
    I have tried the 3 different boot arguments without success:
    -v cpus=1 npci=0x2000 kext-dev-mode=1 nv_disable=1
    I guess I’m doing something wrong..
    Here is a picture of the verbose (-v):

    With thanks,

  13. Worked like a charm on my P9X79 Pro with x79 SSDT! Even USB 3.0 works! The only problem I’m experiencing is when I’m trying to run two GPUs at the same time – GT9500 and GTX570. My machine is built specifically for video editing, so I was using GT9500 as a GUI and GTX570 as a processing card. I can still run both of them, but Yosemite shows only 512MB available RAM on my GTX570 when I’m running it along with GT9500. When I take 9500 out, Yosemite shows 2 gigs for GTX570. Haven’t done tests to see how it affects performance, but 9500 is so old, I need to replace it 🙂 Anyway, thanks for your great work!

  14. The Kexts are linked to in Step 6 part 5 highlighted in the “here” this sentence:
    Note: Generic Extensions can be found Here if needed
    I guess Generec Extensions = kext file

  15. Hi,

    Thanks for all the efforts! I tried so many things!
    Now it’s almost working 🙂
    I did all the steps, the installer worked.
    When I reboot, I still need the USB-key…
    I always have to go around the clover boot screen, selecting my HD and reboot with my boot flags.

    Did I miss something?

    Kind regards!

    • You installed Mac OS X.

      Now you have to do Post Install. What Motherboard do you have?

      • Gigabyte GA-X79-UD3.
        OSX is working fine.
        Only the Post Install didn’t work.

        • Please post in the x79 DMG section what the issue is and we can address it from there. Talk to you soon.

        • I have the same problem….
          My system is Lenovo G50-70 with
          Intel(R) Core(TM) i5-4210U CPU @ 1.70GHz, Socket 1168 BGA (0x6), Intel(R) HD Graphics 4400…..
          Thank you for the nice work ….I have installing exactly as you write the OS X Yosemite, but i don’t understand the “post installation” in 11 part, and 1. I have problem with Boot (only boots from USB ) 2.I must fix power management ??

  16. Hi,

    Trying to install Yosemite on my Asus N53SV, but got stuck on part 7. I can’t seem to disable CSM, nor can I change secure booting to Other OS. Do I need to update the BIOS? It says it’s version 2.01.1204 (2010), maybe that’s it? I can enable UEFI Boot, but that doesn’t seem to work. It doesn’t recognise the USB drive as a bootdisk.

  17. Hi Andrew,

    I plainly followed your instructions and was able to install Yosemite on my HD but I don’t a network. How do I install the network?

  18. Hi,

    I had to reinstall my USB drive. (I want to install Mavericks)
    Strange enough the Clover.command file doesn’t work this time.
    When I click it, my terminal opens and I have to type in my password.
    After I do that terminal shuts down.
    When I click the Clover.command file again, terminal opens and shuts down immediately.
    I restarted my system again, the same happened.
    I’m installing my USB drive on a macbook Pro with OSX 10.10.

  19. Hi,

    I’m trying to install 10.10.1 on my X99 system.

    Gigabyte X99 Ud5 Wifi
    GTX 770

    I made the Clover boot USB according to your instructions but when I try to boot into it, the computer immediately restarts. I never get to Clover.

    One other question. I can’t find a kernel on the 10.10.1 installer. How can I insert the patched kernel into the installer ? I checked hidden files and never had that problem with 10.9.5

    I have the machine running pretty well with 10.9.5 use a Chameleon USB to boot.

    Thanks, Mick

  20. Hey Andrew, so I followed your guide step by step and managed to get the installer working with the nv_disable=1 flag, but when te installer reboots to finish the installation it gives me a kernel panic.
    Please Help!
    I’m using an Asus Z97 A motherboard
    Intel core i5 4670K
    And a GTX 970

  21. Yay it worked, Thanks Andrew!
    But I have one (possible) last question:
    After I installed OS X, set up clover etc… I wasn’t able to boot to my already existing Win8.1 partition, the screen stays black with a blinking cursor.
    BTW: Thanks for the awesome work, man!

  22. What do I do after I installed Yosemite? Like do I need to install drivers? Also, my graphics are super glitchy and slow. 4930k, Sabertooth x79 and GTX 970.

  23. Quick clarification between install guides: the Haswell.dmg guide shows one should check off the PartitionDXE-64 in the Clover install customization, but the guide on this page (Section 1, Part 4: Clover Bootloader Installation, #13) leaves it unchecked.

    Is PartitionDXE-64 specific to Haswell installs?

  24. I’m having issues getting to the installation “10.10”.

    Using the newest clover “v3” and followed the guide, the USB works but even with provided bootflags, it wont go past the loading screen, and at some point the screen just goes black, the PC doesn’t go to sleep during this process though.

    Haven’t found a solution to the problem yet.

    Running RIVE board with Intel I7 3930k and Nvidia Geforce GTX 780 card. 4 x 4gb G.SKILL ripjawZ RAM.

    What can I do?

  25. Hello again, forgive me for my ignorance, I addressed the issue, the config plist wasn’t replaced with the one from the x79 dmg. Apparently it worked by doing so, since it only copied itself and didn’t replace… How dull of me x)


    • Lesson learned and great job finding the solution.

      • Yes. Now I’m currently having another problem that i’ve tussled with in 3 hours maybe.

        I’m having trouble with booting the installation from the HDD i’ve installed it to. I’m using clover, just like on the USB stick.

        I pretty much followed the same steps as if it were the usb i was installing things to, but perhaps that isn’t right?

        What should I do from here?

        *This time i’ve checked what I know could be the issue, i’m absolutely clueless as it seems*

        Thanks again!

  26. gtx 650, evga x58 1st gen i7 pcie airport/sata3

    Only dsdt patch applied manually w/out clover: hdmi audio, worked good on mavs.

    Used some of the clover acpi patches until it was working ok and not crashing in mavs. Experimented with them.

    Could not get into desktop w/video for XX then decided to let it finish installing w/out the video and went shopping. I come back and there is video and all is working but on restart, once again gets to DT and no video. once in awhile i see it load video but often just crashes at the desktop without a crash message, (seems at the point when the card flicks desktop on) I am confuzzled on this one.

    • Can you be a bit more clear. Thank you.

      • The method was to let the install osx app straight from applications upgrade install to keep settings after making a copy of mavs to the new copy. It did boot the third time in the install proccess and worked but video sometimes/sometimes not kicks in at desktop more often not. I just now let clover auto config plist and it worked once but on restart got the same. Not sure if taking out the rt variables section rom/mlb which I had changed from mac pro to imac to stop the tymcedriver blockage had anything to do with it

  27. tried web drivers, not good. But with nv_disable it does produce some video.

  28. There was a repeated message in verbose before crash something like: bug in external booster

  29. I finally managed to get my setup running 100%. now my question is, what is the process to install windows onto a different partition? Thanks 🙂

  30. Hi there,

    I tried to install it on my system but after making usb I restarted my computer in usb only apple picture is showing on the screen with a scrolling circle.
    my system sep are as follow:
    Gigabyte gaming 7 motherboard
    CPU G3258 OC on 4.2
    GTX 760 graphic card
    I used the Haswell Dmg to install but when I was creating my Usb on Audio command my macbook pro yosemite gave me error that apple didn’t sign something so I used the command file above in this guide.
    I am waiting and saving for my CPU upgrade to i7. all components I bought after looking in tonymac buyer guide.
    Thanks in Advance for you hard work and help.

  31. Hi Andrew,

    Firstly, thank you for all the work you’ve put in.

    I have a Gigabyte GA-Z97X-UD7 TH and a EVGA GeForce GTX 760 4GB, with one 4K monitor attached to the graphics card not the motherboard.

    I have the latest motherboard bios “F4” but I’m not able to get past part 7 of your guide. I’m not able to disable CMS, however I am able to change secure booting to Other OS. The CMS settings on my motherboard can be either set to, “Always” and “Never” The following is what happens:

    If Other OS is selected, CMS is greyed out and set to “Always”. If secure booting is set to Windows 8, I can change CMS It to “Never”. I have even tried setting secure booting to Windows 8, changing CMS to “Never”, then changing secure booting back to Other OS, but after I save the settings, reboot and go back into the bios, it reverts back to “Always”.

    Are there any other settings you recommend changing in the bios; like:

    XHCI and EHCI handoff, enabled or disabled?
    Thunderbolt security set to Unique or Legacy mode?
    Should wake from thunderbolt be enabled or disabled?

    Thank you

    • You must change one at a time in the BIOS saving and restarting after disabling CSM, then back to the BIOS to change to Other OS.

      DO NOT change any other setting in the BIOS other then changing Thunderbolt Security to Legacy. DO NOT change any other setting.

  32. Hey, my i have:
    NVidia GeForce GTX 460 (1GB DDR5)
    AsRock H55M-LE

    I’ve just installed yosemite 10.10.1 with clover, but i had to install it with “nv_disable=1″. Now when it’s alredy installed i also have to use this boot option to see anything on my screen, but when i type my password for osx and press enter nothing happens. just waiting and waiting, and nothing new.
    Can you help me please? 🙂

  33. Oh, i should add that in “About Mac” section my GTX 460 is working and i can fin all information about it there. I think the only problem is that osx is using default graphics driver, not this Nvidia one, but even after nvidia web driver instalation and driver choose it doesn’t work..

  34. Hello, thank you for taking time to write the guide and help us noobs out. Everything was working fine until the last step. I was able to boot to OS X fine. I shut down and then turned the computer back on. After entering my password I get stuck with the loading wheel along with the spinning beach ball. I let it sit for 20 minutes and it just stayed there. Can’t seem to find anything on this subject other than swapping out a video card according to a previous comment. That seems pretty ridiculous considering that I’ve already boot to desktop. Do you have a solution to this other than getting a new video card? I was thinking about reformatting and disabling the login prompt. What do you think?

  35. Hello! Thanks for the guide! 🙂

    It’s almost everything clear. But:
    – When I install the Clover on the USB, should I install with these settings, what is here in install guide, or with settings what is on the Haswell DMG (Files->Step 1->picture)?
    – In postinstallation I just repeat the steps, Clover install, config.plist, SSDT, kexts?
    – Where is the DSDT, it’s recommend for my mackintosh? i7 4790K and Gigabyte Z97X-UD5H, I use CPU’s graphics(HD 4600)

    • Use the Install Guide for install settings. And the DMG for post install.

      Some systems may require a SSDT/Config/Kexts from there respective DMG to boot into the installer and should be used as needed.

  36. Hi Andrew,

    Thank you for the response. I tried your suggestion but to no avail. CSM support keeps reverting back to “Always”. I checked out the manual, which states as follows:

    “CSM Support
    Enables or disables UEFI CSM (Compatibility Support Module) to support a legacy PC boot process. Always Enables UEFI CSM. (Default)
    Never Disables UEFI CSM and supports UEFI BIOS boot process only.

    This item is configurable only when Windows 8 Features is set to Windows 8.”

    Any ideas?

    Thank you.

  37. System: Asus x99 Deluxe / i7 5820k / GTX 970 / Win 8.1

    I want to install Yosemite. From reading the intro paragraph, I won’t be able to do that directly due to Clover not supporting Kernel injection on 10.10. But I am confused as to how go about it. Can you please clarify:

    If I install Yosemtie using a Hackintosh, I must first install a pre-Yosemite version (using this guide + X99 dmg post install) then upgrade to Yosemite?

    Thank you in advance, this will be my first Hackintosh install.

    • Install 10.10.1 using a Real Mac or a Hackintosh that supported UEFI Booting. Once booted in post install apply the DMG and after that is done put the drive into the x99 hack.

      • Thanks. I will be using a Mac Mini from 2009 to install Yosemite, as per the guide, then transfer the SSD over to the X99 computer after everything is completed. I have a question regarding the installation of the video card driver (GTX 970). Do install the drivers for it in the Mac Mini or do I do that after the SSD drive is in the X99 build?

        Much appreciated.

  38. Hi
    I did exactly what you did in the installation guide but when booting with USB i got a message “Reboot and select proper boot device”

  40. Hi Andrew,

    Seems as I cannot disable CSM, can I move forward? What are the implications?


  41. I went ahead and installed without disabling CSM, (I don’t think I had much choice as it would not let me disable it) and all seems to be ok. I can boot into Yosimite but I can only do so via the USB drive. If I remove the USB drive and try to boot, I get the following message:

    “Reboot and Select the proper Boot device or insert Boot Media in selected Boot device and press a key.”

    Can you help? I’ve obviously missed a step or two, but not so obvious to me 🙁


    • You need to set the UEFI version of the drive as the primary boot. Also if you leave CSM enabled you need to configure the settings to UEFI so it sees your drive as bootable.

  42. I’m still having trouble by booting from the HDD with clover.

    Using the USB works, but if i do it from the HDD it hangs and reboots instantly. I’ve used the same instructions as if it were to be done on the USB for installation.

    What can i do?

    • Still OSX 10.10

    • Sounds like you did not complete post install.

      • I believe I did complete it before even booting up the HDD for the first time from the clover USB bootloader. Checked twice on that now.

        I suppose I could try repeat the steps again and see what I can discover from that, but Im pretty positive that I’ve done things correctly.

        I will do a complete reinstall and report back asap.

        • I figured something out here.

          After the installation finished, i installed clover, and followed the steps in the dmg for my board “RIVE”. Everything seemed to go smoothly.
          I’m using another clover version since it got updated a few days ago, it behaves differently than the previous one “3095 i think it was named”, when i used the previous version it instantly rebooted if i tried to boot the HDD “weird since it booted fine with the USB” but I’m now able to boot fine with the HDD boot loader, and I’m writing from the hack as we speak. Runs smoothly at the moment.

        • You need the HFS Driver provided in the install guide.

  43. Got the evga x58 board going with the gtx 650. Was fussy and still is, but thanks for the nv disable hint. Seems needed to boot in safe mode and repair permissions.

  44. ‘For installations onto systems that require the use of a modified Kernel you must install using a Real Macintosh Computer or a Hackintosh that supports UEFI booting as Clover Kernel injection does not currently support Mac OS X 10.10. This includes x99 and AMD based systems.’
    Does it mean that i have to prepare the USB stick with e real Mac or that i should plug the HD that i want to use in real Mac before pluging it back in the Hack?

  45. Everything seems to be working, thank you for all the guides and your assistance.

    I have one issue; when the coupler goes into sleep mode, after a while of it being in sleep mode, it reboots. I have also noticed that as soon as it goes into sleep mode, I hear the fans raving up and slowing down.

    Any help would be much appreciated.

    Thank you.

  46. I followed the steps above, inserted my flash, turned on PC. I only get an apple logo. I think the system is frozen. Sadly the documentation on “enter boot flags” and even the answer to other q’s on this subject have no meaning to me. I see no “options” to enter flags for my lga 2011 mb or to turn on verbose to see what is happening. I click on all the clover buttons before executing boot, but no where do I see a flags or options selection. A screenshot would have been helpful in the tutorial for these “btw – enter flags” or “switch to verbose” options. Thanks for all your research on this subject.

    • You failed to follow the Install Guide so your results are expected. Go to the Clover Options Menu and enter the flags or do the suggestion in the guide and install the Config list from the DMG. Follow the Guide.

  47. Is it ok to use Mac OS X on VM instead of using a Real Macintosh Computer or a Hackintosh that supports UEFI booting ?

  48. I don’t have CSM int the BIOS Settings to set it off
    here’s a the BIOS Screen:

  49. I have asus x99 deluxe and intel i7 5930k and asus 770 gtx im stuck at pci configuration begin i tried all flags npci=0x2000, npci=0x3000, -f, -x ,-v,nvda_disable=1, cpus=1, dart=0, PCIRooUID=1 all same result stuck at pci configuration begin

  50. Dear Andrew, i’ve spent a few hours with attempting to install 10.10 to an asus z97-k. it has only it has no extra videocard whatsoever. it stops at about 30% when booting the yosemite installer. here is a screenshot where it got stuck. can you please suggest?

    • Make sure the Kexts are installed in EFI.

      • Dear Andrew, I’ve found out that this halt on the “DSMOS has arrived “relates to some sort of hardware protection (DSMOS = Dont Steal Mac OS).

        It relates to a mismatch of the motherboard chipset and the fakesmc and config.plist files.

        I’ve used the Haswell.DMG files of yours ( this: ). i used the two kexts from there and the config.plist file from there. The ASUS Z97-K will not boot with these (DSMOS).

        Your description also mentions a list of compatible motherboards, but there’s no such section. Or am i missing something?

        Anyway, i wonder what could you suggest at this point. Thanks!

  51. Hi Andrew

    (my components are listed at the bottom)
    I was directed to Hackintoshing by LinusTechTips and so for my hackintosh installation, i used OSX 10.9.5 mavericks an myHack. i installed the os to my flash drive. I used myHack to make it a bootloader. I booted of the flash drive. I successfully reformatted the boot drive in the OS X installer. i loaded up the boot drive and it got stuck on these parameters:

    when I was booting up the installer and boot drive i used these parameters:
    -v npci=0x2000 GraphicsEnabler=No
    and lastly I’ve set upgraded my motherboards BIOS once and for this install i booted it up in default settings.
    is there any suggestions?

    My system specs:
    asus z87 pro LGA 1150
    nvidia geforce gtx 760 2gb

    This is my first Hackintosh and having some problem installing Yosemite 10.10.1. I have a Gigabyte Z97X-UD5h and I’m using Clover v2k_r3113
    I’m getting the following error “unable to find river for the this platform: \”ACPI\”.\n”@SourceCache/xnu/xnu-2782.1.97/ioki/Kernel/IOPlafformExpert.cpp:1590…..

    At this point the computer gets stuck.
    Thanks for your help

    • Use the Clover Config file on the Haswell DMG.

      • Hi Andrew,
        Thank you for your quick response. I used the Clover Config file on the Haswell DMG as you suggested. I’m not getting any error message anymore however the system keep looping between the Clover main menu, the white Apple logo with a progress bar and the light blue Apple Logo. Here are sequence of events.
        Turn system on > Clover Main Menu appears > Click on External > White Apple logo appears with progress bar after a while system reboot and it takes me back to the menu with the Apple light blue Logo > I click on the Apple logo > I get the white apple logo with a progress bar after a while system reboot again > Clover Menu with External Appears > White Apple Logo with progress bar > loop.
        Thanks for your help

      • I’ve put the bootflags just as described but I still get to the white Apple Logo with a loading bar (which is not loading at all). That’s where the system gets stuck. Nothing happens.

        Trying to install Yosemite. Will be transferred to a Fusion Drive later.

        Any suggestions?

        When I put the -v boot flag, I get the message: OS not set yet.

  58. Hello Andrew thanks for all this great work.
    I have a question.
    After I do this:
    Run the Clover Command file and the USB Installer will be automatically created:
    After my password the Clover Command automatically just close.
    Any idea why?

    • Sorry, I find the Problem(:

    • Because you did not complete one of the steps prior to the steps listed before this step.

      • Hi Andrew,

        i did follow yr guide exactly except your link to the 10.9 mavericks DMg does not work, MAvericks is not available on the appstore anymore 🙁 atleast here in south africa, but i even checked the US app store, it is not there either. APP apple now only let u redownload the osx mavericks IF u had it in yr history.
        So i downloaded the original untouched appstore version from a 3rd party site. and its in my download folder. Im guessing the clover command file does not SEE the dmg hence the closure.?
        Please can u help. I sent u the screenshot of my downloads folder

        • See. You lied to me:

          “Hi Andrew, im following your steps exactly to the tee” – Greg

          If you did not download 10.9 in the past you can no longer get it. So install 10.10.

          I can not nor will not support anyone who obtains a non legal copy of Mac OS X.

  59. Hi Guys,
    I installed Yosemite and the system is working well except for the following issues:
    1. I can only reboot into the system if I have the Clover Installer Usb Drive inserted. As soon as I remove the Clover USB drive the system fails to boot.
    2. The monitor appears “dither” on the login screen. Everything is fine as soon as it goes to the desktop
    3. I installed the Nvidia web driver but the system keep defaulting to the OS X default driver

    Thanks for your response

  60. Hi Andrew,

    Just wanted to thank you again for your efforts – just upgraded from Mavericks to Yosemite (Rampage IV Black, 4930K, GTX 770). I was originally using Chameleon, now swapped over to Clover with your guides, which were extremely easy to follow!

    I also wanted to give a heads up to anyone with a similar set-up as me – I had issues getting in to the installer and was getting kernel panic. You may need to disable bluetooth and Wifi from BIOS. I’m not sure why this is, but it seemed to have stopped panic and the rest of the process ran extremely smoothly. It may even be a better idea to load optimized defaults and then apply the BIOS changes needed (would that be right?)

    Secondly, to get proper speedstepping working on the 4930K I had to make sure the SMBios was a 6,1 Mac Pro. Before this I was only getting 2 states. Follow Andrew’s DMG and guides down to the letter and everything is flawless.

    Thanks again Andrew, awesome work!!

    • You just had to use the Clover Config on the DMG to get past the Wifi and BT issue with Clover.

      MacPro 6,1 SMBIOS has issues with some Nvidia GPUS not working at all so be mindful when saying to use something.

      • Thanks for the clarification Andrew,

        For my combination above 6,1 works well. I am also using your OC ssdt-1 and it’s perfect.

        One question while I have you: My usb 2 internal headers work fine, though using the 3rd ROG_Ext header for usb isn’t working. I had this working in Mavericks, but have no idea what may be the issue with Yosemite. Any ideas what I should look at?

        Thanks again!

        • Its a IRQ bug. I Need to add a patched DSDT to fix this to the DMG. It is on my to do list.

        • Hi Andrew,

          Thanks! I thought that was the case (conflicting with the HPET IRQs), I went to remove AppleHPET.kext to test – and sure enough it worked. I replaced the kext and made a patched DSDT. Let me know if you want me to e-mail it to you.

          Thanks again

        • Email me what you did and we can compare notes.

  61. Hi so I am trying to hackintosh my girlfriends computer and I followed your instructions very carefully multiple times but for some reason every time I try to do this step, 4. Boot into the UEFI Mac OS X Install USB: clover always restarts after the bar loads up around a third of the way. I copied the correct kexts and copied the correct config file as well as added the NVIDIA SSDT file since the GPU is GTX 750 ti all from my Haswell DMG which matches my motherboard: Asus z97-C as well as set up my bios correctly. I am currently using the newest clover which is r3128. I have been stumped for hours with no luck finding any solutions. If you can help me I would be super happy.

  62. RE: CSM

    The issue with CSM not switching to “disabled” might have something to do with the graphics card not fully supporting EFI. I have two older cards, a GTX560 ti 448 and an HD6870, and have the same problem with both in two identical motherboards. See this thread:

    • Correct. I have a AMD 6870 that I flashed a UEFI ROM onto it. The other ROM is flashed for EFI for a Mac Pro. Also some Boards can use Intels onboard UEFI ROM GPU with the Deticated Card that does not Support UEFI and still allow UEFI. In my guide I have it listed to be disabled by defualt as most poeple installing on a newer board will have this ablity. Thanks for the Feedback.

  63. Hi, Now everything is working just fine but my case usb and all my usb 3.0 didn’t works. Any Idea???

  64. My Supermicro X9DAi with two E5-2670 with Yosemite/Clover always hangs on boot with hyperthreading enabled. Without hyperthreading, it works perfect.

    Similar problem to the comment of fkenned1 and Kevin de la Cueva on the old blog:

    Bootloader is Clover UEFI. Everything runs like a breeze, but I am not able to enable Hyperthreading.
    With Chimera I got Kernelpanic on Boot with mp_cpus_call_wait Error.
    Now with Clover and AppleIntelCPUPowermanagement.kext installed (FixHPET=off/on and FORCEHPET=off) I got “panic(cpu 0 caller 0xffffff7f82018cc9) : No HPETs available…CPU(s) configured incorrectly”
    Kernel Extension in backtrace:
    After that I tried to remove AppleIntelCPUPowerManagement.kext and AppleIntelCPUPowerManagementClient.kext. It hangs then at “Mac Framework successfully initialized using 16384 buffer headers and 10240 cluster IO buffer headers”.
    Also sometimes it hangs at FakeSMCKeystore: started.
    I boot with arch=x86_64 dart=0 npci=0x3000 kext-dev-mode=1 slide=0
    So far no success. I also tried to change ACPI Status from S3 to S1 or disable. No success. May anyone has a clue and could point me in a direction?
    There was no Problem with Mavericks btw.

  65. Hi Andrew, thanks for your reply.
    Unfortunately, cpus=30 is not working, only cpus=15. Seems like 16 logical cores are the max. I tried also to disable Package Cores to – for example 4, enable hyperthreading and it works. If I limit Cores to 6, enable hyperthreading, It fails…
    Also Clover FakeCPUID Patch set to 0x0206D0 (instead of ox0206D5) is not working.

  66. Why my system hang on boot on the asus republic of games logo when disable CSM on Bios.

  67. Hi,
    after a weird fight with the clover settings and the motherboard, hyper threading now works with your patched kernel.
    To sum up:
    1. Exchanged Kernels – got Kernel panics.
    2. I remembered that I created DSDT.aml with clover “F4” when hyper threading was disabled.
    3. I recreated DSDT.aml with hyper threading enabled and exchanged the Clover patched DSDT.
    4. Hyperthreading worked but my LAN (8086:1521) I350 with I210 Driver stopped working.
    5. Messed around with the clover settings (exchanged smbios Imac 12.2 with Mac Pro 6.1 which ceased my NVIDIA GFX from working) until I wasn´t able to boot anyway, weird graphics on the verbose screen, pixels all over, Fault CPU Errors – had to restore from Time Machine. Then, after restore, suddenly I got mp_cpus_call_wait again, in opposite to “no HPETs found” as earlier.
    6. Tried to recreate DSDT with all hyper threading cores enabled, copied to ACPI/patched, created SSDT with ssdtprgen script, also to ACPI/patched. After that I was unable to boot, kernel panic – AICPM Panic.
    7. Pulled out HD, deleted SSDT, rebooted, accidentally with HT on, booted – OK
    Now It runs 32Logical Cores, but in System profiler, It only shows 16 Cores.
    Geek bench went from 27000 to 33400

    Actually, I don´t know what happened exactly. Tried to much. Also weird is when in Clover Options, CPU tuning menu, Clover shows only 1 CPU and Cores enabled is always 8 no matter if HT is enabled or disabled.
    Also Turbo and Speedstep is showing up there, but I don´t recognize Turbo with HWMonitor.

    However, here is my EFI Folder as ZIP

    Best regards and thanks a LOT!


  68. Hi Andrew,
    Thank you very much for all your help. I finally got everything working. I’d like to create an image of my current settings. What do you recommend?

  69. Hi,

    Firstly, thanks, as this is the second time i’ve installed OSX using your guides and X79 SSDT files. After working out that my out dated BIOS on my P9X79 WS was causing a kernel panic on this install, i’m now up and running.

    My one question was regarding the overclock SSDT or stock SSDT for my 3930K.
    Do i have to do an exact overclock, or close to 4.5GHz, in order to use that SSDT?



    • Good to hear.

      No, the SSDT is good up to 4.5 GHz. So anything under that it will work fine.

      • Great, thanks Andrew, much appreciated 🙂

      • Ok, my last question, i hope…!

        I’ve overclocked my CPU (3930K) to 4.5GHz, all working fine and showing as that in Intel Power Gadget, although it is pegged at that speed.

        The power usage idles at a nice 12-13 watts, and bumps right up when stressing the CPU.

        I take it that the power state bumps it up and down when needed, but speed stepping is pretty much a no no on the 3930K LGA2011?

        Thanks again,


  70. Hi Andrew,
    rampagedev became my defaulf hackintosh guide, thank you!
    I have a x99 ud4, i7b 5960x
    Part 6.5: The kexts that you refer are the ones on the platform image(X99/Files/Step2/kext) ?
    Part 8.3: -f seems to be necessary too.
    Thank you for the great job!

  71. It’s a P9x79 WS running with a 3930K processor.
    I installed the latest BIOS and installed the AppleIntelCPUPowerManagement.kext using Kext Helper and the SSDT-1 from the 3930K folder into the relevant Clover folder. I’ve tried both the standard one and the overclock one, both with an overclocked and non-overclocked BIOS.

    I’m wondering if i’m overclocking wrongly in some way? Things have changed quite a bit in the new BIOS….



  72. And i noticed that the full machine description doesn’t exist in Clover, just MacPro5,1.

    Is it worth using Clover Configurator to fill in the missing blanks for machine description, processor, serial number etc?

  73. Hi Andrew,
    got yosemite installed by following your guide step by step. Everything works except for sound.
    Worked the haswell.dmg also step-by-step but always getting this error on step 4:

    • Email me for the BETA SSDT.

      • Hi Andrew,
        the beta ssdt.aml you send me works like a charm, thank you. i was able to change the patcher script found HDEF and replaced them with HDAU, saved it and i works. Sound is no longer my problem.

        Now my only “problem” is that the automatic boot doesn´t work, i tried all version of:


        LastBootedVolume or MacHDD


        Any idea? Thanks in advance!

  74. OK, just a heads up, i created my own PM SSDT using ssdtPRGen and replaced the one supplied on the DMG for P9X79 WS v2, and all is now working.
    Seems like it may have been some slight difference in my machine?!

    I did also get some errors about the CPU ID maybe not being set correctly and the mainboard ID too. Is this normal?!

    Thanks again dude..

  75. Hey Andrew,

    I used the proper config.plist from your X79 dmg, which adds npci=0×2000
    The installer start but then I get a kernel panic
    Verbose mode gives me what looks like a GPU related issue:
    I get several ‘RadeonSensors: Still waiting for accelerator to start’
    Then ‘Error unable to find ATY/,bin_image’
    Thx for your input

    Specs: X79 Deluxe / 4930k / HD 6870

  76. Hey Andrew,

    No luck.

    Boot flags: npci=0x2000 kext-dev-mode=1 ATI=True FBName=Duckweed

    ATI = YES
    Intel = YES
    NVidia = NO

    What do you think? Thx a lot

  77. Thx Andrew, no luck either. Im out of ideas here…

    • Btw I had no problem installing 10.9 with Chameleon.
      I could go with it again, but Clover does look like the future to me.

      I see many people succeeded with the same brand as mine (Sapphire), I have no idea where things get wrong on my side…

      • Email me about this with the Board info and I will add the injection code for the GPU into the SSDT for the board. Then you can try to boot to the installer with that.

  78. Thanks very much Andrew, will do. I’ll add a pic of my screen in verbose right before kernel panic.
    The board is a X79 Deluxe, tell me if you need other info.

  79. This is the proof My Hackintosh 100% w0rking 24000k geekbench score wow this is incredible. Thanks Andrew

    My Hackintosh:

  80. Hi! Thank you for your guide. I did everything you said untill booting. I have a black screen with an apple and nothing else. Maybe I did something wrong and I needed to add more kexts (I added only Generic Extensions you added). I don’t know…

    And where do I need to type it? I see only interface of Clover boot with options, uefi 64 and etc…?

    LGA 2011: -v cpus=1 npci=0x2000
    LGA 1366: -v cpus=1 npci=0x2000
    LGA 1150: -v
    LGA 1155: -v

    Needed for 10.10: kext-dev-mode=1

    Nvidia GPU issues use: nv_disable=1

    Now I use Mavericks, as I work in Logic the problem is Logic Pro X doesn’t see 6 cores after I insalled Mavericks many months ago… So I want to try Yosemite. Maybe I didn’t added some kexts there.

    My config:
    Intel 4930k
    Asus x79 Deluxe
    Nvidia GTX 780
    Motu 828mk 3 Hybrid – ( usb audio interface)

    • Just install the Clover Config and kexts from the x79 DMG for install else look in clover go under Options in Clover to set the flags as needed.

      • Thank you. I installed the first part (until the disk utility) and and after reboot it begins again. I do something wrong. Do I need a new BIOS for my Asus X79 Deluxe?

      • PCI configuration begin and… nothing…

        Do I need to try with Chameleon?

        • Please follow the directions on the Guide. If you do there would not be a issue.

          You did one of two things:

          1. Did not enter the Boot Flags
          2. Did not enter the Boot Flags properly.

      • Thank you. I don’t actually understand how I did it))) Some combinations but Yosemite works, but without internet and I don’t know should I need to do something with my GTX 780…

      • Thank you. I have installed everything. The problem is I have 3 hardware synths, they connected via midi cable and usb to my Audio device (Motu 828 mk3 Hybrid) . Audio/Midi setup sees my Audio device, even Axiom (USB Midi keyboard) but it can’t see my synths…. Probabbly too many usb ports or what? So when I look for them in Logic Pro X 10.1 it can’t see them. Do I need to find some kext or it’s because of my Asus x 79 deluxe?

      • I understand that just few USB ports work, because when I reconnected synth to the front USB panel of computer it will work…

      • One more question: how to boot Windows 7 and Yosemite from Clover without changing CMS and “boot from other OS” in BIOS? Every time I need to change preferences in BIOS to boot Yosemite or Windows 7. I tried to boot Windows 7 from Clover menu – it doesn’t work.

        Thank you.

  81. Hi Andrew,

    First thank you very much for your website and support on this.

    I’ve been trying to install Yosemite using your guide for x99 MB. I’ve setup a USB key (I hope) by following your guide but I get stuck on a “PCI Configuration begin” and no matter which boot flag I’m using I’m still stuck at the same point.

    You should find a picture of my screen using the link below:

    Thank you for your help.

    Kind regards

  82. Thank you Andrew for your quick reply. Sorry for the question but what do you mean by “the Roll Back kexts on the DMG”.
    Thanks again

  83. Hello everyone,
    I doing everything you worte here. But i’m still don’t succeed.
    I’ve i7 5960 – ga-x99-ud4 – gigabyte gtx 960
    The bios is the new version F12
    And i think i did all the setup in the bios.

    Please enlight me i just buy this computer for hackintosh for 3000$+

  84. I have 2 macbook pro and 1 other hackintosh with 10.9.5

    The new hackintosh for 10.10
    Tell me what did you mean roll back kext? From where to where?

  85. Btw the colver boot up and apple logo with loading bar but its stuck and after few seconds it’s doing restart.

  86. I do it.. It’s show me apple logo and after that i see “no entire״ symbol

  87. I’m see every flag i do after few second apple logo do restart but only when i used this flag: cpus=1 the apple logo stuck forever and don’t do restart..

    what can be the problem ?

  88. Hi Andrew,

    a week or so ago I emailed you my dsdt (X9Dai) and ssdt and asked if you could take a look at it. Did you had time to take a look regarding Speedstep and Turbo?

    Thanks a lot,


  89. I have a problem. Once installed Osx you say:
    2. After the Initial Installation the System will Restart.
    3. Boot into the Clover Installer Usb Drive and Boot into the Installer again.
    4. Once booted the Installer will automatically run and install Mac OS X.

    But when it finish the installation, it doesn’t restar well:
    1-Screen goes black
    2-PC doesn’t POST so it doesn’t actually restar
    3-it stucks on black screen and if i press any key, it appears a bold dash in the top left corner of the screen, and any key i press displays symbols on screens.
    4-I tired to write boot flags in this screen without success.
    5-If i manually restart the system, and boot into Installer, it doesn’t continue the installation.
    5-It makes me start a new Installation.

    What could be the problem? I followed all your steps, could be the Graphics kext? Or i only need to wait until the blackscreen automatically go away and restart the system? Thank you!

  90. successfully installed and working yosemite. I’m not able to boot the HDD without USB bootable installer. Does we need to connect the USB installer before booting HDD.

  91. Hi Andrew,

    did you got the files (x9Dai)? I sent it at the 5th.

    Best regards,


  92. Hey Andrew,

    Does the X99 DMG support Gigabyte X99 UD5 with 5960X to install from UEFI USB native install media created from the guide? I would need a patched kernel for 10.10?
    I’m having memory allocation issues on boot from the USB stick.


  93. I followed post install as per guide 3 times.
    1 Boot to the UEFI Mac OS X Install USB:
    2. Select the Partition you installed Mac OS X to.
    3. Use the arrow keys to select the drive that Mac OS X is installed to.
    4. entered boot flags
    LGA 1155: -v
    Needed for 10.10: kext-dev-mode=1
    5. Boot into the drive that Mac OS X is installed to:

    After booting into HDD, then removed the USB and restarted from OS X.
    After restarting it shows no bootable media found. Pls guide me. I want to boot the OSX without inserting USB.

  94. Hello guys,
    I’m having a problem with the Yosemite instal on my Asus Rampage IV extreme, with EVGA GTX 780 ACX, and 3930K cpu, I’ve made the installer using the guide and I’ve tried it like 20 times I’ve remade the installer like 5 times. I use the boot args ” -v -f npci=0x2000 cpus=1 kext-dev-mode=1 nv_disable=1″ what happenes is it loads the verbose screen loads nothing too out of the ordenery then it gets to a line like GeForse sensor: waiting for accelerator to start couple of seconds like maybe 45-60 this message repeats like 4-5 times then there is a crossed out circle and the screen lines become unreadeble the letters are distorted and thats it. I am thinking its the video card issue because its not quite like the KP i have gotten thouse too trying to use the modifyed PM kext in the instaler, so its not KP but it looks like everything loads just before it gets to the welcome screen the video card throws some thing off. any one experiance this? and andrew how did you get your 780 to work?

  95. does any one have issues with getting into installer yosemite with GTX 780? im getting a wierd freeze at the end of the verbose boot with a crossed out cercle and the line of code becomes distorted and unreadeble, the last lines of the code are something like GeForce sensor, waiting for accelerator to start.

  96. hey Andrew,
    I’m trying to install this to my hackintosh
    My mobo: i7-4930k and nvidia gtx770, asrock x79 extreme4
    I was just wondering if instead of the generic kexts, should I copy all the kext form the post install
    All so should I include all the patch from post install to the USB
    Finally there seems to be 2 SSDT in the post install for x79DMG, the SSDT.aml and SSDT-1.aml, should I replace the file or keep both?

    • And also, after I’ve done all the post install, do I need to install the graphic driver following the graphic guide again?
      I mean install all the retail versions or web driver etc…

    • Yes, I actually say that they may be needed at the boot process and to use them as needed.

      Do not use the SSDT for install.

      • Thanks Andrew for this tutorial, everything run great now
        Just a couple of issues:
        1. The computer doesn’t recognise my CPU as i7-4930k but a it shows a xeon5 instead, however the clock speed seems correct, should I be worried about this?
        2. The graphic shows correct information event without the injection step in your other guide, should I continue to inject?
        3. I can’t seem to get the audio to work, my audio device is: realtek ALC 898, the command file keep saying: there is no IOReg/HDEF,… How to fix this?
        4. The ethernet (BCM57781) card doesn’t work (with your IONetworkingFamily kext) after update to 10.10.2, can you provide me with another working kext?
        5. Can’t boot directly from HDD, must use the USB <– still have this problem 🙁
        That's all, apart from these problems, everything runs perfectly 🙂
        Tks again

        • Please follow the READ ME on the DMG as what you have stated shows you have failed to follow the READ ME. Please do so. Your creating your own issues by not doing so. And stop looking at cosmetic items.

        • Finally got it to work 🙂
          The bios didnt recognise my MacHDD as uefi and there was no boot option, got that resolved and that fixed the audio and ethernet problems now with all the SSDT enabled.
          However, I have another HDD and now yosemite won’t let me use it. It keep saying it doesnt have efi partition system and force me to format it
          The drive is 1Tb and I don’t have another one to back up, do u have any way to resolve this? I can’t find any solution on the internet.

  97. Thank you for sharing your wisdom. The guide is very thorough, I followed it right up to here: Part 6: Kext Installation

    4. Open the Folder of the Mac OS X Version that the Clover USB contains.

    5. Copy the Kexts into that folder.

    Which kexts? I read the guide several times and these kexts have not been referenced before.

    I downloaded your X99.dmg for my Asus Deluxe (5960x)

    • You can use the ones from the DMG or the ones in that part as if you read the whole step Generic Kexts are provided in a link. Best of luck.

      • Thanks. I disabled CSM as per your guide and now the machine doesn’t see any boot devices!

        I have Asus Deluxe (1305 BIOS)
        GTX 760
        32GB RAM

        I’m at a loss.

        • That means that the USB was not correctly made. Please re-follow the guide, read and follow each step. Make sure not to skip any step(s) as doing so my result in the issue you have. Let me know if you have more issues.

        • Changing to ‘Other OS’ in the BIOS seems to have done the trick. System now boots to the Clover USB.

          I need to add kext-dev-mode=1 boot flag, how do I do this? I’m used to Chameleon and just typing it over the boot partition.

  98. Hi,

    I use to have my X99-UD4 with i7-5930K and GTX-970 running fine with Nvidia Webdrivers. But since updated to 10.10.2 and latest webdriver I have OSXAptioFixDrv AllocationRelocBlock Errors. I tried different versions of OSxAptioFixDrv but I can’t pass by this with my new installer made per guide here.
    Any clue?

  99. I’m having this with the USB installer so there is no CUDA nor webdrivers concerned. The strange thing is it was running fine until I updated to 10.10.2 and then suddenly the OSXAptioFixDrv errors occurred and now it is impossible to use Clover as bootloader running F12 BIOS latest Clover and 10.10.2 on USB. Chameleon will boot but I don’t want to fall back on that of course. I can Install with Chameleon USB and after login use Clover but at first reboot OSXAptioFixDrv error.
    I’ve run cache rebuild command and so on nothing seem to help any.

  100. Hey I’m still stuck with a X79 Deluxe / 4930k / HD 6870

    Andrew was kind enough to add the injection code for the GPU into the SSDT for
    this board but I still couldn’t boot into the installer with it.

    Here is what I get:

    I’m rather confident everything is set up correctly, so I’m wondering if anyone esle has the same issue with the same setup…


  101. Hey guys, i was wondering does any one have any suggestions on how to overlock asus rampage iv extreme and 3930k, i can always use the BLK method but i was wondering if there any other ways that work better giving more speed steps. i do have the ssd-1 and the power management kext installed but it does not seem to be working for some reason.

  102. Hello,

    I tried the tutorial above with my new ASUS Z10PE-D8 Motherboard, I disabled VT-d as asked, put the drives into AHCI mode. But the kernel boot stops at
    [PCI configuration begin]
    RTC: Only single RAM Bank (128 bytes)

    I googled around, but found no real solution.
    The bootflags I tried to use, but always with the same result:

    A bit more info about my system:
    Motherboard: Asus Z10PE-D8
    CPUS: 2x XEON 2620 v3
    Memory: 2x 16GB DDR4
    Drive: Samsung M.2 256GB PCIe SSD (Had the exact same results with a standard Samsung Sata EVO 1TB drive)

    Any help would really be appreciated!
    Best regards!


  103. 1. Problem with part 8 Booting. After following all steps to preparing the flash, installing clover, copying Kexts and running the command file and disabling setting in Bios and secure boot option change, I restart with flash in and clover boot menu opens up.
    I only see two options there. 1. boot windows from… and another boot windows from reserve.. I dont see anywhere to boot from the flash?

    2. When i ran the clover command file, terminal opened up, asked me for a password, typed it in, and after i pressed enter, it did something fast and vanished.. i didnt see any copy files status…

    3. I also have a problem understanding what i should do with the mavericks 10.9 5.32 gb install dmg, so i merely copied it to the root folder of the clover flash drive. (you dont mention what to do with the downloaded osx in the first step.) – yes this might be a stupid question. Sorry for the pain.

    4. Also, since i dont have a Mac, to do these basic tasks, i installed a mac osx version in Virtualbox which im using to format the flash, install clover, after which, it automatically mounted EFI, after which i copied the generic kexts into 10.9

    Thanks again. Basically ive gotten to the clover boot screen when i leave the flash in..

    • Your not following the Guide. Only closes if you do not follow each step prior to running the file.

      If you obtain Mac OS X from a non Apple source it will not work.

      • Hi Andrew, im following your steps exactly to the tee :(. It is not a non apple source osx. i downloaded from the app store. (the 10.9 dmg.) where am i going wrong?


        • There is no DMG from the App Store.

        • Ok, well is that why the clover command file doesnt know what to write to the flash?
          As i explained your Mavericks link from the appstore is no longer available. I think they removed it. This is what i have:
          X99 Deluxe Asus
          i7-5820k processor
          GTX 970 evga

          So i thought installing Mavericks might result in a more stable system than yosemite. so when i looked for mavericks in the appstore with your link it was not available.

          Is there anyway i can extract the contents of the mavericks DMG or would you recoommend i just download the Yosemite. does it result in a stable build> is there anything not working.

          New to all of this so just trying to make it as simple as possible, hence i wanted to try mavericks rather than yosemite. Your adivse is very welcome and i really appreciate your help so far.

        • There is no x99 DMG for 10.9… its just x99 DMG. Please review.

  104. Hello, thanks for a great guide and DMG. I’m having a slight problem upon first restart. My system:

    Asus X-99 Deluxe (BIOS 1305)
    5960x CPU
    GTX 980
    32gb (8x 4gb) DDDR 3000mhz
    Yosemite 10.10.2

    I followed the guide as per your recommendation for X99:

    1. Installed OSX on an external USB3 device using a Macbook Pro.
    2. Setup a Clover USB stick using instructions in the X99 DMG, using the SSDT and ALL the Kexts.
    3. Edited VoodooTSCSync so that IOCPUNumber=15
    4. Pasted the supplied Kernel from the DMG (using the 10.10.1 Kernel because there was no 10.10.2)
    5. Deleted the Kernelcache in Startup on the HD.
    6. Used your Clover Config file and didn’t edit it in anyway. (flags are npci=0x3000 nv_disable=1 acpi=off nvidia=false)
    7. Followed your BIOS recommendations regarding CSM and ‘OtherOS’ option.

    Booted from the Clover USB and then booted OSX from the external USB3 drive on the hack box. It booted first time into OSX no worries.

    I clicked about a bit, changed some desktop view options – including the name of the computer in Sys Pref> Sharing. Thats about it.

    I didn’t install the Nvidia web drivers yet..

    When I rebooted I got a consistent KP.
    panic(cpu 0 caller 0xffffff000041e88a)

    Do I still need to patch the Kernel somehow? Did I miss a step?

    I’ve tried removing kexts, editing the config, changing flags as well as some of the other known fiddles such as the various incarnations of the AptioFix file but nothing changes.

    I have a picture of the KP I could send you for more info..

    If you could suggest any tips or help that would be fantastic!


    • Please re do the install and this time follow my set instructions. Your editing files that SHOULD NOT BE CHANGED. If I do not tell you to do something please do not change them.

      Also do not use the Modded Kernels as Clover now support native patching and is in the Clover Config list.

      • Hey Andrew, thanks for your reply!
        I will try again. So just to confirm, I will not edit the VoodooTSCSync this time. And when you say do not use the Modded Kernels, do you mean just skip the step where I pasted the supplied Kernel from the DMG? Thanks for your help, really appreciate your assistance with this.

        • Forget editing that kexts. If I don’t tell you to do a step do not do it.

          Skip that step for the kernel. That step was left in to make sure the edit worked for my test users with Clover. That part will be removed from the DMG later on.

  105. Great, thanks for clarifying. Thanks for your swift responses, really appreciated – I’ll give it a go and let you know. B

    • Hi Andrew,

      So I gave it another go (I didn’t patch the Kernel and I didn’t edit VoodooTSCSync kext) and managed to boot consistently into OS X and it worked even on multiple restarts using flags: npci=0x3000 nv_disable=1 acpi=off nvidia=false. So thank you for your help!

      I then installed web drivers and my flags are now: npci=0x3000 nvda_drv=1 acpi=off nvidia=false.

      Now I’m getting stuck at ‘OsxAptioFixDrv: Error – requested memory exceeds our allocated relocation block’

      I’ve tried OsxAptioFix2Drv.efi, and also another one I found online called OsxAptioFixDrv-X99.efi which gave slightly different errors but never got into the proper verbose mode.

      I’ve tried also without nvidia=false but still the same.

      If you have any suggestions it would be much appreciated. Thanks for your time,


      • Most of the flags that you use do nothing or have not been in OS X for 3 OS versions.

        That said please review the x99 Support page on how to remove the cache.

        • Hey Andrew, so I believe my flags are now set correctly with npci=0x3000 nvda_drv=1 kext-dev-mode=1.

          I read the X99 page about removing the cache. I can find reference to removing the kernel cache but am unable to find clear instructions (including elsewhere on the web) about how exactly to remove anything else. I believe it is ‘rebuilding kext cache’ you’re referring to. Would you be able to point me in the right direction?

          Thanks so much,


        • npci=0x3000 is useless as that flag has not been in the kext it is for for 3 os versions as I had said before. Please only use the flag provided in the x99 DMG Clover Config File. Else you can and will have issues. Only saying this so you don’t use the wrong flags.

          nvda_drv=1 can be added to the DMG’s file.

          Remove the Cache file in the location listed on the x99 support page.

        • Hi Andrew,

          So I have followed your instructions on the boot flags and am now just using npci=0x2000 nvda_drv=1 kext-dev-mode=1.

          I also removed the kernel cache as instructed on the X99 support page but I still get the same ‘OsxAptioFixDrv: Error – requested memory exceeds our allocated relocation block’

          Any other suggestions? This is pretty much the brick wall right now 🙂



        • Welcome to early support. Nothing else you can do.

        • Hello fellow builders, my system is:

          Asus X-99 Deluxe (BIOS 1305)
          5960x CPU
          GTX 980
          32gb (8x 4gb) DDDR 3000mhz
          Yosemite 10.10.2

          Did anyone with a similar spec manage to get this working with Nvidia web drivers yet?



        • Thats awesome news Andrew!
          What did you do to get past the ‘OsxAptioFixDrv: Error – requested memory exceeds our allocated relocation block’ problem that seems to occur only after the installation of the web drivers? I have read somewhere that it may be because there are too many kexts in use. Is that possible? Would doing a reinstall and leaving out, say the bluetooth kexts help? Or was there another way you managed to fix it? Is this what you describe as a ‘memmap issue’ ? Are there any ways to force it to use memory that does not exceed the allocated relocation block? Thanks

        • Try updating to the latest BIOS.

      • Genius.
        Don’t know how you do it dude but well done and thank you. Big respect for being the Mackintosh Yoda.
        I installed the latest BIOS for my mobo and it works a charm.
        No more mem map problems.
        The only problem is hanging on Bluetooth Kexts so I removed them and now not a problem.
        Donating now.
        Thanks again mate, keep up the good work 🙂

  106. It seems some file are missing
    At step “Part 6: Clover Configuration”
    2/ Download Clover Config Files here.
    And it tells me “The requested URL /Clover Config Files was not found on this server.”

  107. Hi Andrew,

    I installed Yosemite on my Z97x-ud5h BK 1.1 following the install method. I am using a GTX970 GPU which requires the nv_disable=1 flag… After completing the post-install, do I still need to use this flag?

    Another question regarding post install – I followed your instructions, then after completing the post install – restarted the machine and upon logging into Mac Os (entering password) the busy wheel continues indefinite and I never get to the desktop.

  108. Hi Andrew,
    Do you know if it can work with a videocard not compatible uefi.
    I have a gtx650 not uefi so I must enable CSM.
    I tried 3 times to reinstall clover and I always stuck on first boot at
    Fault CR2 —> fault cpu 0x0
    I tried all bootflags
    (x99-a / i7 5820k / gtx 650)
    Thanks a lot

  109. Hi,

    Just to be sure at 6. 12. Copy the Kexts into that folder.
    Do i have to copy Kexts of all my components ? I have a ACL992 sound and an atheros network ? (And look for them?)


  110. Hi Andrew.

    I managed to get to part 8 step 4….

    If i select the USB to boot… screen goes blank and if i esc out of there it goes back to the clover screen. SO going to replace the file u asked us to replace on the EFI partition now. Also where do i set those boot flags that u mention in part 8 for my x99 system.

    • Are you booting in verbose?

      • Andrew, for the first time if i try boot to flash, blank screen, then when i press escape it comes back to clover. i then go set the boot arguments u suggested for my lga2001 and then the message below comes up. (see my last post with the error message. I have followed your steps EXACTLY. I even got the x99 DMG frm yr site got the kexts and config plist and replaced them on the EFI partition.

  111. Thanks Andrew, so the raison is out there…
    please, do you have an idea of where the problem comes or where I have to search ?
    Thank you

  112. Hi Andrew,
    I’m having issues with the USB3, they are listed on the “System report” using the kext “GenericUSBSHCI”, I even reinstalled it using the Kext helper b7 but it’s not working. It has power, as I’m able to charge my phone, but no device is recognized, pendrive or external hard drive.
    Please advise,
    Thanks for all your hard work

  113. I have Yosemite installed following your guide, but my USB 3 ports are not working. Gigabyte X79, i7-3930k, GTX780. Any suggestions?

  114. Failed to follow the guide. Thats what the photo’s showed me.

    • Please could u help point out where I’m going wrong? We are trying to follow yr guide but may not have the insight u do. Would be nice if u cud show me where I’m going wrong And help with a solution. I’ve asked about 4 times now and u have not helped but just brushed off asking us to follow the guide.

  115. Can i chat to you on Skype. im attempting this again as i type this… would be much easier on skype? to send u screenshots

  116. ok Andrew. ive done it again…. now boots into the black screen with white apple. few seconds later apple screen becomes a cancelled sign…. and stays there. THis time i didnt do any boot flags…

    :/ this is painful…

  117. re doing the USB again. will revert

  118. Hi Andrew.

    This is what ive found so far.

    the black screen with the white apple only loads if in clover i install the OSXAPTIO2DRV 64 file. if i install the one u list. it does not boot and shows the error message about some resource alloc.

    Next problem the black screen wt apple logo has no progress bar, reads the flash, and then the apple turns into a cancel / no go sign like this..

    and that is the end of anything that happens.? any tips? again ive rebuilt this USB 3 or 4 times.

    Im tempted to ask whether it will be better to install Mavericks? but its still an X99 system, so wondering if ill run into the same problem…

    I think im gna call it a night here in SOuth Africa 🙂 my OSX adventure has hit a brick wall and i have fought hard …. please assist lol…

  119. Hi Andrew. that seems to have done the trick. Looks like the Bios was out of date. Updated it and the errors dissapeared. I got the APple screen, loading. but goes only halfway….. then reboots…. and im back at clover… ie doesnt seem to finish and get to welcome screen.

    Thanks for your assistance thus far.

  120. added bootflags fr LGA 2011 and nv_disable=1 and looks like im finally at the welcome install screen…. blood sweat and tears… lets see if its worth it

      • Mr Kern!

        Just an update! after my whole friday and saturday night slaving away, i finally installed and booted into yosemite.!! Wouldnt have made it without your help, so i thank you. Just a few issues.
        1, The system is extremely sluggish, im guessing because of the display driver.
        2. I installed the web drivers and rebooted with the flag u asked us to boot with but it refuses to boot with that flag. And it never keeps the USE nvidia driver setting either.
        3. in the config.plist in the graphics key section is see intel is true… is that a problem…
        4. its a GTX 970 from EVGA.
        5. I did all the X99 DMG post installs. ALso replaced the kernel for 10.10. (but the yosemite installed is 10.20? is that still fine?
        6. Initially i had WIndows 8.1 installed to a sep SSD. I could boot to it from my Clover usb… now after installing OSX.. no chance of booting to windows 8.1 anymore, even if i try boot to it directly from Bios… Corrupted?
        7. How do i post an IOREG so u can see why system is sluggish?

        Thanks again!! so close!!!

        • 2. Look at the photo for the Menu Setting and read the caption.

          3. No. Has no effect. Do not edit the config other then adding the flag for the retail drivers.

          5. Don’t use the old kernel. The clover config has the patch for it so no need for it with 10.10.2 and onwards.

          6. No idea what you did to windows.

  121. Hello Andrew,

    If I have 2 SSD and I want to set as Raid 0, do you think is it hard to do? Do i have to modified anything? Please advise.

  122. Hi Andrew,

    I have the following setup:

    Asus X99 Deluxe
    I7 5820K
    EVGA GTX 760

    Trying to install Yosemite 10.10.2 onto an X99 system. I used Clover v2.3k r3185 and I’m using a MacBook Pro to create the USB drive. In Clover I checked “Install for UEFI booting only”, “Install Clover in the ESP”, “EmuVariableUefi-64” and “OsxAptioFixDrv-64”.

    I downloaded the X99 DMG, copied and pasted Config.plist into /EFI/CLOVER/ and AppleGB, AppleIntelE1000e, FakeSMC, NullCPUPowerManagement and VoodooTSCSync.kext into /EFI/CLOVER/kexts. I disabled CMS and changed to Other OS in the Bios; basically following this guide to: Part 8: Booting, subsection 3.

    I’m able to get to the Clover Boot Manager, I hit enter and get the Apple logo and a progress bar, which does not move at all.

    I believe I’ve followed it correctly but maybe not. Would you mind pointing out what I missed or did wrong.

    Thank you,


    • You are not following the install guide if you see a logo. Please READ and follow the set instructions on the Install Guide.

    • Hi Sophie,

      after just struggling through this myself, the part you’re going wrong is the x99 dmg. x99 dmg used for POST install.
      so copy the generic booting kexts into the 10.10 folder, part 6 point 12, link in the sentence below that 🙂 and the config plist from part 6 point number 2 🙂

      also when u boot. edit the clover boot options in clover. make sure cpus=1 and nv_disable=1

  123. Hello Andrew,
    I have :
    i7 3820 (SOCKET 2011)

    With your help I got my system running Mountain Lion a couple of years ago – with minor problems, the main one being I can’t get my account authorised on my Hackintosh to download OSX updates.
    I can get Yosemite running well using the old method, with the same issues. I wanted to try a Clover install to see if it would bring my system closer to operation of a real Mac (and unlock iMessage etc). It is OSX10.10.1 I have.

    I’ve followed the method listed here twice and I think I’ve done it to the letter, but it will not boot from the EFI partition. I can only boot into OSX if the USB stick is inserted. If the stick is missing, my boot takes me straight to BIOS.

    CSM is disabled in my BIOS. Secure Boot only allows me either to enable or disable Secure Booting, I can’t select an OS.

    I’ve tried making disk0s1 the active partition via Terminal, my best guess is the bootloader is not on the EFI partition but when it comes to these things, my best guess doesn’t count for much.

    Can you please advise? Very probably I’ve missed something obvious.

    Best Regards


    • AsRock issue. Need to install with Legacy Method of Clover.

      • Thanks for the advice.
        I’ll maybe jump to a different mobo and socket in the next few months and try a clean hack of EFI Yosemite then.



        • Hi, I have the same board and had the exact problem but I managed to solved it
          The problem is bios doesn’t see the HDD as bootable
          –> So u have to go to bios and just add a boot option, navigate to efi/clover/bootx64.efi
          and choose that boot option

        • Thanks Phan, I’ll have a look at that.

          Best Regards


        • Andrew, I built a new system, i7 4790k, z97mx-gaming5, GT 740.
          First install I was having problems with rebooting that I couldn’t troubleshoot. However, reformatted drive and carried out a fresh install as per this page – works like a dream. Fantastic!
          Only thing I haven’t done is install the mobo SSDT. In your guide it says to replace the existing SSDT with the one in the Has well DMG, but as far as I can see there isn’t one to replace?

          Best Regards


        • Use the one on the DMG.

      • Hi Andrew

        I built a new Hack, GA-Z97MX-Gaming 5, Nvidia GT 740, i7 4790k.

        It runs great. Onboard audio works, access to App Store everything really.

        However, often on boot, it restarts after about 7 seconds. If I leave it at the login page, the cursor flashes 7 times, then the system reboots. This happens a lot. However if the system allows me past that 7 second mark, it is very robust with no crashes.

        I’ve tried getting reports from Console, but (unless I’m looking in the wrong place) there only seems to be reports for successful boots. It’s like the reboots simply didn’t happen.

        Any ideas how I can find the source of the problem?

        Best Regards


  124. Hello! I have an ASRock P43de, an Intel Core 2 Duo and NVIDIA GT430 2GB ram. Currently run OSX Lion on this system. I tried to install but when it starts booting OSX Yosemite after a few seconds the system will restart. I tried several combinations of boot flags but the result was always the same. Can you give some advice? Can I install Yosemite on this system? Thank You!

    • You will Need to use Clover in Legacy mode. Is that how you have Clover installed on the USB installer?

      • Hello, again!
        I finally managed to install Yosemite after some BIOS settings – DEP enabled in BIOS (== DEP Data Execution Prevention). Now NvidiaGT440 video card is fully recognized but the driver is not installed, or at least I think so, because I can not change the resolution settings. Showing only two options 1028×768 and 1280×968. What can i do? Thank You!

  125. Hi Andrew,

    XEON E5 2680 V2
    CRUCIAL MX100 512 GB SSD
    Crucial Ballistix Sport XT 64GB


    I was successful installing OSX 10.9.5 on this system using your method, thank you. But the audio was janky and noisy and I messed around with the VoodoHDA kext. The system went into a kernel panic and it won’t boot.
    I was able to boot the system using the USB Clover Bootloader and made a carbon copy of the drive to an extra HDD I had.

    I formatted the ssd and retried installing OSX 10.9.5 but this time the USB Clover Bootloader is not recognizing the ssd, there is no drive to choose from. I have used different bios settings but I am not able to see any drive yet.

    Any help would be appreciated.

    Thank you

  126. Hi Andrews,
    I’m trying to install Yosemit on my laptop (asus A42jc) and the installation boot (1st boot) keep stopping at DSMOS arrived
    Plz help me on how to fix this 🙁

  127. Hey Andrew,

    I followed this guide and used the Haswell DMG to do a new build. I have successfully installed Mac OS 10.10.2, patched sound, and confirmed that everything is working as it is expected to. However, I have a really annoying issue where both my GTX 780’s ramp up to 100% fan speed within the first minute after boot.

    I have TWO gtx 780’s, both exhibit the same issue when on web drivers. The issue goes away on Default OS X drivers, however this system was built for the purpose of running DaVinci Resolve, which will not see the cards without the web driver.

    The Two models I have are: ASUS GTX 780 OC Edition (3GB). EVGA GTX 780 Superclocked Edition (6GB).

    On a previous install using clover, 10.10.1, and the previous web drivers, these cards did not exhibit this behavior, but I ran into the AptioFixDrv error on reboot with that build and decided to start fresh, bought a new SSD rebuilt from ground up.

    Any advice would be appreciated, thank you for taking the time to read my post.

    My Specs:

    MoBo: z97x-UD7 TH
    Mem: 32 GB Crucial Ballistix
    CPU: Intel i7 4790k (Overclocked to 4.4)
    VGA: ASUS GTX 780 OC Edition (3GB).
    VGA2: EVGA GTX 780 Superclocked Edition (6GB).

    • Non issue.
      The kext I used are designed to do this so that the fans are not stuck at 19 rpm and cooking your card under 10.10

      • So I would assume there’s no way to have the rpm based on temperature as a variable, rather than fixed 100% rpm?

        Is this specifically an issues with the GTX 780? Or could I switch to a 980 to gain proper variable rpm?

        Thanks again.

  128. Hi,

    Followed the instructions and it installed fine. I didn’t even have to enter any boot flags during any step! The only problem I know of yet is that I can’t get it to wake up out of sleep and restart does not work. I have to do a full shutdown and then boot. Anybody else have this problem?

    Sabertooth X79
    i7 4820K
    GTX 760


    • I do not Support sleep. The Code to address sleep is in the SSDT however due to many factors it may or may not work for you. This should have been posted in the x79 DMG Section.

  129. Hi,

    Can i use the above listed process to install OS X 10.10 on a PC running Win 7 and make it dual boot later on?

  130. Hi Andrew.

    Question on DUal boot.

    Can u recommend the best method.

    I did this :

    1. Install OSX to my OSX SSD, (Seperate Windows SSD was disconnected)
    2. COnnected my WIndows SSD, Installed WIndows (with OSX ssd still connected)

    ALl worked well. first few boots. I went through CLover which had the windows boot option.

    I noticed windows installed a boot manager on my OSX SSD.

    then OSX stopped booting… (just got to apple screen, then no loading sign.. then apple turns into the ghostbusters cancel sign..

    Had to re-install the whole thing.

    DO u reccommend i disconnect my OSX ssd before installing WIndows?



    • You can not have the Mac drive connected when you install Windows. Understand how Windows Installer works as what you have seen is what Windows does…

      • Andrew,

        If I already have Windows 8.1 installed on one drive. Do I need to disconnect it before installing Mac OSX 10.10?

        • If you have to question about doing something then do it the safe way is the rull of thumb here.

          That said. No, you do not Need to. Just dont reformat the wrong drive.

  131. Hi, I am trying to install yosemite on an asrock x79 extreme 4, with an i7 4820k and gtx 780.
    I have the clover usb ready, trying to boot with flags: -v nv_disable=1 npci=0x2000 kext-dev-mode=1

    Starts to boot and at a while appears the error sign on clover.

    What should I do?
    Thank you!

  132. Followed the directions to the letter, but for some reason, nothing happens when I try to use the Clover command file to create a bootable USB disk. Enter the password and the terminal window just closes. I have a fresh download of Yosemite from the App Store. I tried this on my Mac Mini at home and Mac Pro at work (Both running Yosemite) with same result…

    • Nope. You did NOT follow the directions to the letter. Please follow the guide as stated.

      Either you did not download the OS from the App Store or did not Format the Drive as per the directions.

      Please follow the guide.

  133. Andrew,

    I am having issues installing Mac OSX 10.10.2, which is the one available in the App Store right now. I followed your guide exactly and made the USB installer. I replaced the config.plist. Tried the kexts in the Generic Extension folder and/or the ones in the DMG with 8 core only. I also tried with VBoxHfs-64.efi or HFSPlus.efi. I have CSM disabled and secure boot set to Other OS. But no matter what I do, it will stop at “PCI configuration begins” and reboots back into Clover.

    These are the kext that I used:
    -v npci=0x2000 kext-dev-mode=1
    -v npci=0x2000 nv_disable=1 kext-dev-mode=1

    My specs:
    Rampage V Extreme
    Matrix Platinum GTX 980.

    Please help and thanks.

  134. Thanks for the reply. I have a few questions for you to help clarify. If I install 10.9.5 natively on my X99 can I update it to 10.10.2?

    Secondly, like you said if I was to install 10. 10.2 on a x79 system. I just have to go all the way until the installation is complete. Then turn off the system disconnect the drive and plug it back to my x99 and do the post install?

    Thanks in advance for clarifying.

  135. So which procedure is correct?

    1. Install 10.10.2 onto X79 system and post install with X99 DMG.

    2. Install 10.10.2 onto X79 system and post install with X79 DMG. Then move drive to X99 system and redo post install with X99 DMG.

    Sorry for asking. Just want to make sure. Since it seems like there’s no way to download 10.9.5 from the App Store.

  136. Thanks for the guide, flawless installation!

    I have a doubt tho, why not install Clover in the hard drive after everything is done, that way you can boot without using the USB.

    Best regards.

  137. After a few tries, I successfully created a USB installer and installed Yosemite to an empty drive on my Asus P9X79WS BIOS 4701 and Nvidia 580GTX. The BIOS prohibits disabling CSM yet I was still able to install to the hard drive.

    I copied kexts from your current DMG to the EFI patriton on the hard drive with no issues. I had Ethernet working, along with my FireWire 800 card and my Intensity Pro capture card. Onboard audio didn’t work but the Intensity card output usable audio.

    However installing the SSDT and SSDT-1 files cause boot issues on my hard drive. Once I removed from the /patched folder, I could boot again from the hard drive. after a bit of reading forums, I tried holding down on f4 when booting which caused my HD to now not boot at all. Removing everything from the original folder didn’t help. Now can only boot from USB.
    Any Ideas why the SSDT files causing problems?

    • Failed to follow the set guide lines in the READ ME on the DMG. Please perform post install as per the READ ME. Until then I can not debug.

      Also I just did a Install on your board 1 week ago and no issues with the SSDT for the board.

  138. My Mountain Lion install worked flawlessly for a couple of years with your DSDT

    • So Auto is different then Enabled? If I disable CSM the BIOS automatically goes back to Auto. I will try Enabled when I get home and put the SSDT and SSDT-1 files back in the /patched folder on the EFI partition of my SSD and see if that works. Anything else in BIOS I need to tweak perhaps?

  139. You have a 8 core CPU. Must be install using a real mac or on another hack.

  140. Yes I did. Replaced config.plist, installed kexts from X99.DMG, place SSDT in the specified folder. And deleted kernelcache as well.

    • I get the PCI configure begin error when I try and Overclock the CPU so make sure yours is at stock frequency. Also try to disable XMP. Also try update the MB bios see if it helps. B

  141. if that doesn’t work i recall having to remove emuvariableuefi-64.efi on one occasion. this is where doing your test boot on the usb stick before installing to hd really helps 🙂

    • Will try your method and report back.

      Thanks Ben.

    • Thanks Ben!! Finally got it to boot after removing emuvariableuefi-64.efi from both the Clover USB and the SSD. However, the mouse cursor appears to be sluggish. How to fix this?

      • Good stuff. You need to install nvidia web drivers to get the 980 working full speed. andrew has done a guide on here about how to do that and what boot flags to change after you install. If you have probs after installing drivers then put the emu variable file back. You’re close bro! B

        • Again. Your saying you are doing something and not doing it. Your statements and questions do not match what you told us and I can see right thru this. I even made a post about this last week:

          “Also many questions that are being asked are already addressed and clarified in various guides. Many of these questions are in the accicuated guide. That said, we will not answer or assist those users who will not read in full a guide or article. We have no issues in answering questions but we will not spend time on these questions. We can tell who those users and posts are and we will push you to read in full the guide or article. I wish I did not have to address this but this needed to happen. All we ask is for you to read the in full the guide or article and to follow them as well before posting a question. 90% of the work of making a fully functioning Hackintosh is reading.”

          Please do post install as you are not not doing so. IE self created issues. So please don’t lie to us or we will not help you.

  142. It’s all on Andrew dude, he’s the genius and he helped me loads so just trying to help back anyone with similar specs to mine.

    1. It will always say OS X default drivers for reasons I do not know. But if you check in ‘about this mac’ and it lists your 980 and full 4gb vram and you can utilise your monitors full res and refresh then you’re in business.

    2. Gtx 980 doesn’t Rev to full 100% fan speed as far as I’m aware. From what I heard that was the 780. Mine 980 revs up when needed and 4k rendering etc is all good. I Might be wrong though!?

    3. I didn’t have any luck with the audio patch either unfortunately but Installing the voodoohda.kext makes it work but was a bit noisey so I just bought a soundblaster omni 5.1 usb sound card which is great and works natively in OS X and win8.1 without the need to install anything.

    If you need Bluetooth you can pick up a single for £10 that works a treat too.

    If your happy with the help you got from Andrew I would definitely advocate a donation to his website.

    Good luck bro!

    • 1. As stated in my guide under the pic when you set the driver to the retail driver I state this is cosmetic as we do not have real nvram. If we did then this would not be cosmetic. I do not support the Use of rv scripts so…

  143. Andrew, I really do appreciate your work. But I want to clarify one thing, I didnt lie. I did follow the steps as much as possible. And the main reason why I couldn’t boot into the OS was because I needed to remove emuvariableuefi.efi and this came to sense cause Ben pointed that out. Not everyone here is an expert in making a hackintosh like yourself. So please don’t accuse everyone who can’t get their system to work a liar. Even though you have insulted me but because of the work that you put into this site I will still donate.

  144. Hi,
    I decided to build a X99 hackintosh.

    I’ve got some questions:

    1. Is the combo of Xeon E5 v3 + Asus X99-A supported by your guide.
    2. What’s the most up-to-date and working out-of-box (including HDMI, DP audio) graphic card?
    3. Is M.2 PCI-E SSD supported by OSX?


    • Depends on the exact CPU model.

      None. There is no such card. All requires patching. You need to understand how GPU Audio works. Please review.


      • I am considering to buy Intel Xeon E5-2618L V3 , 8 cores 16 threads.

        I guess like 5960X 8-core CPU requires extra jobs to be done?

        In terms of GPU, please enlighten me with some general readings about GPU audio.

  145. I’m Just curious……
    What’s the limitation of Xeon E5 v3 + X99?
    Is a CPU with more than 8 cores supported?

  146. Installing a 4790k / Gigabyte GA-Z79X-UD7 TH system… followed the guide, got the install working ok, but the ‘part 11. post install’ section isn’t clear. It ends on rebooting the system. I know that I now need to use the DMG for my system (Haswell DMG), but I’m kind of guessing as to how I use the DMG. Here’s what I’ve done:

    – Step 1: installed clover on my hackintosh hard drive, using the install settings specified on the DMG, and copied the config.plist file into the Clover folder on the EFI partition.

    – Step 2: Wasn’t sure if the kexts were supposed to go into the clover/kexts folder on the EFI partition, or whether I was supposed to install them with the kext helper app on the DMG… did both.

    – Step 3: Found the folder for my mother board and grabbed the AMD SSDT (I’ll be using a 7970k as a GFX processing card). Copied the SSDT into EFI/Clover/ACPI/patched folder

    Step 4: At this point everything worked except audio… Wasn’t entirely sure what to do with the files in the audio_RealtekALC-master folder downloaded from the link in step 4 … went through the Read Me and ran audio_realtekALC-100.command. Still no audio…

    Have I done this right?? Any tips on getting audio working?

  147. Hey Andrew,
    I’ve been struggeling installing Yosemite on my Hackintosh (with a GA-H87N-Wifi) for two weeks now. Yesterday I found your guide which took me a bit further … but the result was a white screen with the spinning beach ball.
    As I wasn’t able to find out which config-file would fit my system I took the config.plist from the X99 folder. The next problem was that in my UEFI Dual Bios there is nothing that says “CSM” and what can be disabled. Booting the computer takes me to a blue screen with seven icons where I can choose between “Boot Mac OS X from …”, “Start UEFI Shell 64”, “Clover Boot Options”, “Options”, “About Clover”, “Restart Computer” and “Exit Clover”. Where do I have to write the needed boot flags into? Choosing “Boot Mac OS X from …” takes me to a black screen with a progress bar followed by the white screen mentioned above.

    It would be phantastic if you could please help me solving this puzzle.

    • Please read and properly follow the set instructions in the guide. Do not mix and match or deviate from the installation guide.

      • Hi, Andrew. I have OS X Mavericks up and running on my hackintosh. However, I recently tried fixing the audio crackling by installing the voodooHDA.kext. It did not work, and now I cannot boot into Mac without going into safe mode. I deleted all the files it downloaded and installed and emptied the trash. It still does not work. Please help me.

      • Hey Andrew,
        thank for for your answer!
        I did some research and found out that my Gigabyte GA-H87N-Wifi needs Haswell. So I started a new attempt and made a new installation stick. Unfortunately got stuck at the same place when I tried to boot. I assume it has something to do with the settings in my UEFI Dual Bios. Part 7 of your installation guide says that I have to disable CSM, but I still can’t find that option in that UEFI Dual Bios. Booting with F12 takes me to a list with boot devices. Choosing “Clover start boot.efi …” takes me to that blue screen I mentioned above. Choosing “ UEFI: JetFlashTranscend 8GB” also takes me to that blue screen.
        What am I doing wrong? I am pretty desperate …

        • Gigabyte did a horrid Job with there BIOS. The Settings are in there.

          Just boot to the UEFI Version of the USB Installer from the Boot Menu.

        • Hey Andrew,
          that’s what I did … and it took me to that blue screen where I can choose between “Boot Mac OS X from …”, “Start UEFI Shell 64”, “Clover Boot Options”, “Options”, “About Clover”, “Restart Computer” and “Exit Clover”. How should I proceed?

        • Remake the USB installer as the USB was not made properly.

        • Hey Andrew,
          I’m glad that I finally made it. Yosemite is booting and running … but only if the USB stick is attached.
          I read in several forums that I have to mount the EFI partition and copy some certain files to the EFI folder on my HDD. The problem is, that my USB only contains the installer app. Furthermore I can’t see any EFI folder on my system drive …

          It would be great if you please could help me once more.

        • See dmg for you socket and read the read me.

  148. Hi Andrew,

    I have a question about Step 6. I’m currently making the USB installer for Yosimite, and I have a question about the kext section of it. For this step it says use Kext Helper B7, drag the kexts into the app, and allow it to easy install. My question is: what exactly does this do? It does not allow me to select which drive I want it to target, so is it installing the kexts to my /system/ folder, or the one on the USB? Or do the kexts automatically install themselves on the EFI boot drive?

    I’m a bit unsure of this step because the kexts in the DMG and the link in Step 6 are different.

    Just trying to understand more, so that I can learn. Thanks for writing the whole guide, I’m using it because of the px79 pro support. Excited to get it working!

    • You are not following the Install Guide based on what you said.

      • Hi Andrew,

        You’re absolutely right, I mixed up steps and didn’t realize that x79.dmg was only for post-install. I got clover boot EFI installer to start properly now. However, now I’m stuck at Missing Bluetooth Controller Transport. I’ve read that this isn’t a bluetooth error, but a graphics problem. I’ve tried nv_disable=1, but I can’t seem to get past that step. Only other thing I did before getting to this problem is changing out the HFSPlus.efi to get it to quit insta-rebooting.

        Thank you!

  149. Hi,

    I’m trying to install Windows virtual machine using Parallels Desktop 10 on an X99 system but without success. Has anyone else experienced the same or know of a fix?

    My system setup is as follows:

    Asus X99 Deluxe (latest bios)
    Intel i7-5820K
    Corsair Vengeance LPX 32GB 2666
    EVGA GTX 760 4GB
    256 Samsung 850 Pro
    Corsair AX860 860W

    I am able to install Parallels but not a virtual machine. When I try to either install Windows 7 or 8.1 or boot an existing Windows VM (created on another Hackintosh, which runs just fine may I add) I can neither get Windows to install because it runs so slow; no errors or crashes, just extremely slow that it would take forever to install. When I try to launch the Windows VM that was created on my other hack (i7-4771 Haswell / Gigabyte GA-Z87X-UD7 TH, I can’t even get it to load, it would just take too long. I ended up quitting parallels about 45 minutes after waiting for Windows to boot, at which point the Windows boot screen was still intermittently moving at a painfully slow pace.

    I’ve also tried installing Windows under VMware Fusion, but got the same issue.

    Any help would be much appreciated.


  150. When someone already has a running version of 10.9.4 with Clover, recovery partition (cheers) and HDMI audio, what’s the suggested method for going to 10.10.x?

  151. Trying boot the a 10.10 installer on a X99-A with 5930K and GTX 960 but I always ended up with sytem uptime in nanoseconds. Any ideas? Thank you!

  152. Hi. Following the step 4, I couldn’t find my cpu (4820k).

  153. So I have the 10.10.command running on the USB drive, and it is doing the “Copying installer files to disk….” for about 15 minutes now. The USB drive is flashing along so data is being written or read, but how long should this take? Will this window close when it is done? I have the app store downloaded install of the osx Yosemite in the app folder.

    • Let me answer myself here. It will close when its done. Mine took about 20 minutes. You might want to use a better USB drive then I did.

  154. Using Sandy Bridge MSI P67A-GD55(B3) latest BIOS (4.3).

    Tried install as suggested, but with verbose boot, it freezes after first USB initialisation. I think I might need VoodooTSsync or boot with CPUS=1 temporarily. Just read about this today… something you may wish to mention. Also, I was not aware of the HFSPlus-64.efi situation either! Nice guide.

  155. Thank you so much for this comprehensive guide Andrew. It has made it so that i have my new X99 hack up and running on 10.10.3 in no time. But I have a serious problem that I can’t find much information about on any hackintosh website/forum actually. First some information:

    Gigabyte X99-UD4
    Intel 5820K
    Gigabyte R9 280X
    16GB Crucial Ballistix 2400Mhz
    1TB Samsung SSD drive
    5TB WD drive

    I have installed and reinstalled four times now. Either by following your guide exactly, or by installing Yosemite native on the SSD with SATA to USB controller and through my Macbook Retina, then post install Clover, patching the kernel manually and so on. Everytime I come up with the same result:
    Yosemite works fine and boot properly.
    Ethernet is working with proper kext
    Audio is not working (I have tried step 4 numerous times, but just cant seem to get it working properly. It shows up in system pref. but no sound.
    Anyway my REAL problem is this:
    After som time of use (can happen upon login aswell) the machine freezes completely. With that I mean everything freezes except the mouse which shows the rainbow wheel. There is no way of getting it to respond again except manually powering off. I experienced a similar problem on my Retina 15″, but just not as frequently. Do you have any suggestions on how I might fix this? Is this not a hack related problem since I know of similar issues with native Apple computers.
    It is often related to safari use or for example opening a stack of files on the dock.

    Hope you can help me. I would appreciate it alot!!
    Kind regards

    • Failed to follow the dmg documentation.

      • Hi again Andrew.
        Thank you for directions, but it’s not fixing the problem. I clean installed it once more, were realy focused on getting all the details, and follow every step both in the installation guide and in the X99.dmg guide, but no it is still happening. I can actually trigger the error by clicking the download stack on the dock 6-8 times and the system freezes. Do you have any other idea?

        To sum it up in short:
        – Creating the USB boot installer (format, install clover, run script, copy config + kexts, replace VBoxHFS)
        – Set BIOS settings
        – Install Yosemite (bootflags, format, install)
        – Post install:
        1. Install Clover (correct settings)
        2. Replace config on EFI partition with the one on x99.dmg
        3. Open Kext Helper (add AppleIGB, AppleIntelE1000e, FakeSMC, NullCPUPowerMangement, VoodooTSCSync, GenericUSBXHCI) – also tried with and without Asus bluetooth kexts. Password, easy install
        4. Copy SSDT (UD4 / AMD) to ACPI/Patched
        5. Remove install USB
        6. Restart
        7. Patch audio with audio_alc_x99-hda-100_patch.command
        8. Restart
        9. Delete KernelCache
        10. Restart

        Am I missing something? Cause I can trigger this freeze like clockwork. 6-8 click on a stack on the dock and the system freezes completely only able to move cursor with spinning rainbow. Power down computer is the only solution.

        I ran Apple Service Toolkit Storage Diagnostic on my SSD to check if I had bought a faulty drive. It actually failed, but I read online that this could happen with some types of SSD’s like my Samsung EVO without anything being wrong. The error AST displayed was “SMART attribute to check not matched.”

        Thank you for all your help! Hope you have some insight in what im doing wrong here. I hope I have overlooked a simple step in the installation process, but I don’t know.

        Kind regards

        • Did you redownload the Mac app and try that?

        • I’m currently preparing a new USB installer with a fresh downloaded Yosemite installer that I will try, thanks for the tips. While it is working I read through your documentation on X99 and AMD once more and I read in the AMD Graphics Guide:

          “Part 3C: Clover Bootloader Injection
          1. Using Clover Bootloader, the following Boot Flag must be used to enable Full Graphic Acceleration under Mac OS X:

          FBName=Framebuffer (Not Required)”

          I have not been using ATI=True as a boot flag. Should I be using that? If that is the case It seems possible to me that my freezing could be related to graphics since as it freezes artefacts sometimes appear on the screen.

          Thank you!

        • Not needed with that GPU. If you want a FB you can but you don’t need to mod anything on the installer.

      • Nevermind. I tried ATI=True as boot flag, but it didn’t do anything with the problem. Reinstalling 10.10.3 with new installer file as I write this. Hoping it will do the trick.

        • Don’t mod anything with my files. Not needed to mod with your GPU.

        • Ok thanks. Same happened again after fresh install of OS X 10.10.3 (new installer, followed your guides exactly, no modding no nothing else than just what it says in the install guide and x99.dmg documentation. It seemed to work fine. I used it for a while and could use safari and clicked on a stack in the dock 20-30 times without any problem. Then I opened Spotlight and everything froze. Can I send any form for log from the console or anything else to help debugging?

        • Make a video and send the log.

        • Sent you an email with log and video.

        • You forgot full System specs!

  156. It must be possible to implant VoodooTSsync into the installer for those with 9+ cores? I guess you need a different .dmg for every one tho (12/16).

    Just an idea.

    • Stop going to websites that lie about this driver. Do not touch nor modify any driver that I have on the dmg. I have these drivers in there for a reason and are cerified by us. Failure to follow this will result in a broken install and we can not debug.

  157. Hello!
    Thanks for this wonderful work!
    So I am actually in the process of installing yosemite with clover, thing is, My computer seems to freeze at “DSMOS has arrived”
    I used these bootflags: -v kext-dev-mode=1 nv_disable=1
    I used the haswell config.plist document
    My hardware: Gigabyte Z97 SLI, I7-4790, two GTX 760, two 8GB HyperX 2400MHz CL11, Samsung 850 EVO 500GB SSD

    Do you have any ideas? did I do something wrong?
    Thanks for your help!

  158. At Part 5, no.4 should there be something like “installation completed” ? You did not provide a screenshot how that would look like. Before this I tried the tonymac Unibeast method which didn’t work out so far. Is this the part where the Yosemite files are copied? I am not sure.

  159. Hi , my mackintosh updated itself to 10.10.3and now it restarts after bootloader in a loop , i tried reinstalling multicast and extra folder but nothing helps, is there a solution? Thank you.

  160. Do i need to reinstall OS X again?

  161. Hi Andrew.

    Can we now say that Installing Yosemite on an Asus Deluxe X99 system w/ GTX 970 graphics. does not work with the Clover method. Because after we install Nvidia web drivers the system after a reboot, the system does not boot because of the mem map error. And as u mentioned, Slice is apparently working on this clover fix. Would it not be wise then to rather edit the x99 guide to mention the cover legacy install method that works. Or if i am mistaken is the mem map an isolated issue.
    However i have a pretty standard install :

    ASUS X99 Deluxe
    EVGA GTX 970
    i7 5820k

  162. Hey andrew, Ive managed to install os x and all the kexts for my machine, but for some reason I cant boot from the HDD, Ive installed clover on the EFI partition but every time I try to boot it gives me a “still waiting for root device” error then reboots, but it boots fine when I boot from the usb.
    GTX 970
    ASUS Z97 A
    8GB RAM
    INTEL 4670K

  163. I had a similar build, and I got stuck at this step also.
    I had to install Clover on my main drive, exactly the same as I did for the Installer, including the config files and kexts. I used Clover Configurator, to access the EFI partition, and made the changes on the system drive, I also had to set the Bios Boot options to boot from the UEFI – drive, (my Bios showed Uefi and plain partitions) once I installed clover.
    I ended up removing the USB to make sure I had the Right EFI partition while loading config.plist and the Kexts.

    • Pretty sure thats not the case, Ive checked several times if all kexts\boot flags were set in the right partition and not on the usb drive.

    • Pretty sure thats not the case, Ive checked several times if all kexts\boot flags were set in the right partition and not on the usb drive, and everything seems normal, really wanna know what’s happening here.

      • Re-install (make sure to Partition the Drive as per the Guide) and this time install the kexts into Clover EFI and not to SLE. See if the end results Change.

      • Did you double triple check that the Bios is using the UEFI clover partition as the primary boot device?

        also it might be the video card, if your system looks like it’s booting but just cycles or holds on a black screen, I ended up adding a step in the build process to remove all the NDA*.kext file on initial build. Once I did that I could get the system to boot, than just had to play around with the nvidia web drivers and Cuda to boot.

        what I did was added boot flag “-s” at the command line


        once that was done. machine booted with terrible graphics but I was able to get drivers loaded.

        • That is not needed. Do not mod system kexts. If you read the Install Guide there is a boot flag that covers this.

        • I tried all of the boot flags listed in the guide nv_disable=1 didn’t work with or without -v and with or without GraphicsEnabler=No

          Although I do freely admit I’m very new to this stuff I suppose I typed at some point, Please list the prefered flag to avoid deleting the Kext files, as I’m pretty sure I’ll be doing this build again before long, I’d like to know.

        • As stated before. Use the proper boot flag.

  164. Hi Andrew,
    I used your guide to install Mac OS X Mavericks. Everything went well. I have a problem I need to insert a new ATTO H680 SAS card into the station and use it in system. Tell me please how I can do that? Thanks!

  165. Look Andrew
    On this mashine
    i7-5930 3.50GHz 6 core processor
    asus x99-a Motherboard
    Nvidia GeForce GTX 780 strix – 6GB / dual 2 cads / not SLI
    always recognize 16Gb of ram memory. I have 32Gb – 4x8Gb
    Use Clover instalation in UEFI mode. I select EmuVariableUEFIx64, OsxApatioFixDrv-64 and use this arguments kext-dev-mode=1 cpus=1 npci=0x2000
    How to fix memory? Thanks in advanced.

  166. Yes I Enabled trust in Clover.

  167. I just want to say, thank you Rampage for your reply in my thread. I have re-installed using your method, and hopefully it will work well. Thank you for your efforts and help!

    – Tong

  168. Hey Andrew,

    I have a great working Hack thanks to your guide. I am trying to add a LSI 4gb Fibre card to it that I harvested out of an old mac pro. I have it physically installed, but it does not seem to be recognized by system profiler OR DPCIManager.

    I’ve looked for drivers, to no avail. Not many people seem to have discussed this on the web, and I’m at a loss for where I should begin to get this working?

    Any advice would be appreciated, thank you for taking the time to read my post.

    My Specs:

    MoBo: z97x-UD7 TH
    Mem: 32 GB Crucial Ballistix
    CPU: Intel i7 4790k (Overclocked to 4.4)
    VGA: ASUS GTX 780 OC Edition (3GB).
    VGA2: EVGA GTX 780 Superclocked Edition (6GB).

  169. Hi Andrew

    First of all A HUGE thank you!

    I have bulid a new hackintosh. By following your guide

    MB: Asus x99 Deluxe
    CPU: Intel i7 5820K
    32 GB corsair Ram

    It all work really well with Yosemite, but I am frustrated that it does not recognise the Ram it says 32GB DDR3 when i have DDR4

    And when i benchmark it with geekbench it’s only 13K

    Do you one know why and how to make it run better?

  170. Hey, Thank you first of all for all your efforts in helping others achieving system functionality.

    Im following your guide to the letter and when I try booting the mac installer from the clover usb key I just get allocation errors.

    My boot arguments are:

    Gigabyte ga x99 gaming 5
    Cpu: intel i7 5930k
    Ram: 64gb DDR4
    GPU: Titan X GTX 12gb

  171. Hi I tried both .commands and terminal seems to crash disappears immidiatelly after launch. 10.9.5

  172. Hi,

    New build (GPU) question, here are my relevant specs:

    i7-4790K CPU
    Gigabyte GA-Z97X-UD7 TH

    Monitors I want to use:
    2x 4K LG 31MU97-B Monitors
    2x Eizo ColorEdge CG241W (not sure I’ll be using these, as they are only 1920 x 1080. I may just stick to the new LG’s I’ve ordered.

    The main use for this build will be: Lightroom, Photoshop and at a distant second, Final Cut.

    Is it true I should go with a Radeon GPU over an nVidia due to the nVidia being slow for Final Cut? What’s better for Lightroom and Photoshop? I’m also looking for something which will work out of the box and that will work well with at least two 4k monitors and possibly one or two 1920 x 1080 monitors.

    Any advice would be much appreciated.

    • Buy a Nvidia GPU as support for the latest AMD cards is not the best at this time for Mac or for Wkndows for that matter (last non beta driver for windows from AMD was in December).

  173. Thanks for your advice Andrew.

    What nVidia card would you recommend that will run at least two 4K monitors and be fully supported? Meaning, I don’t have to do anything, just plug and play or as close to plug and play as possible.

    Thanks again for your help.

  174. Hi Andrew,

    I picked up a EVGA GTX 970 SSC, could not justify the price of the 980.

    To properly install it, do I just plug it into the motherboard? If not I have no idea and would appreciate your help.

    Thanks again.

  175. Hi,
    I’m able to boot the installer and complete the process but when the computer reboots and I relaunch the installer nothing seems to start automatically, the HDD seems to be empty and I can reinstall the OS a second time but nothing changes.

    Any advice?

    Thank you for your tutorial and your help!

  176. Hi Andrew,

    I’ve just installed a GTX 970 and just wanted to run it by you, just in case I missed something.

    After using your guide to install OS X (Thank you very much for all the time and effort you’ve put into it). I did the following:

    1. Installed the GTX 970 into the system and connected a monitor to it. (I still had a second monitor connected to the on-board graphics). In the bios, the “Initial Display Output” is still set to internal graphics – IGFX.

    2. I booted into OS X, downloaded and installed the web drivers: WebDriver-346.01.02f04.

    3. Rebooted, went into the bios and disabled the internal graphics card and used boot flag nvda_drv=1

    4. After booting up into OS X, I selected NVIDIA Web Driver as opposed to OS X Default Graphics Driver.

    Everything seems to be showing up fine in About This Mac -Graphics.

    Is there anything else I need to do, for example not having to keep putting in the boot flag?

    Thank you!

  177. Hi Andrew,

    Thank you for all your help, I was able to do the NVIDIA install without issue.

  178. Andrew,

    Would you you mind explaining what “Section 13: NVidia 900 Series” is about, is it relevant for me? I followed “Section 2: NVidia Retail Drivers Current Method”, Section 3: CUDA” and “Section 4: Graphic Card Tools”.

    As a reminder, I have the GTX 970 SSC graphics card.

    Thank you.

  179. I tried the one on your guide for Fusion Drive. I was able to put in all commands without getting any error messages but in the end it still didn’t work. Do you have a guide for that or a link for me?

    I would be very happy if you could help me with this.

  180. Hi Andrew,

    a few days ago, i have done a posting about my hardware configuration and that i have done through the installation process (step-by-step-guid and x99.dmg). for reasons i don’t know, my post was wipe out?!

    everything works fine here, but the onboard sound and the onboard wifi 5ghz. i would be very appreciated if you or any of your crew could help a noob to solve this problem.

    once again here are my specs:

    asus x99 deluxe
    i7 5820k cpu
    16 gb
    gtx 770

    • We have a Debug AppleHDA on the DMG for this. Install the AppleHDA from the DMG.

      Patch for 5 GHz which is covered in are Wifi Guide. May not work in 10.10.2+

  181. Hi Andrew,

    I have a Gigabyte GA-Z97X-UD7 TH. I followed all your guid and all is great including “sleep”. The only issue I have is “no audio after sleep”. Do you have a guide to fix for this issue?

    Thank you

    • I don’t have that issue. Can you post a IOREG before and after sleep. I am not on the latest BIOS that I do know. Also there was/is a bug in 10.10.3 with that. See release notes for the patch in the folder you downloaded.

  182. Hi again
    I have successfully installed 2 systems (and of course donated 5% of system) but my third system is giving me problems

    File: File: audio_realtekALC-100.command_v1.0.4c
    Verify kext-dev-mode=1 boot flag/argument
    Confirm Realtek ALC892 (y/n): y
    Enable HD4600 HDMI audio (y/n): y
    Audio ID: 0 is not supported, continue (y/n):

    I had some similar problem with the same MOBO before, which you solved with a new SSDT.

    It was because of a BIOS update to F11.

    i-5 4460
    GTX 650 Ti Boost
    NorthQ PSU (2.2 could this be the problem? I would think only sleep would be)
    8 GB Corsair RAM from the other system

    I am using all the new Clover and Haswell.DMG. Have tried with both 1.1 and legacy 1.0 SSDT (I got “no codec detected” both times – though after changing back to 1.1 SSDT I got this new message above)

    hope you can help – and thank you for all the work
    will mail ioreg now

  183. Hi Andrew,
    Your site is great!!
    I build a custom-Hack with these components:
    cpu:i5 4460
    ram:crucial ballistix (2x4gb)
    ssd:samsung 850 evo(128gb)
    gpu:Sapphire R9 270x
    What is your opinion about my system?
    Clover bootloader?
    I think tha the sapphire R9 270X might cause me troubles.

  184. I followed your directions, but once I finished running the Clover install to the USB named Clover, the EFI partition dis-mounted. This contained the files from the previously mentioned Clover install. I ran the 10.10 command script and it completed without issue. However once I re-mounted the EFI partition, none of the files are listed anymore and I cannot start Part 6. Should I just re-install Clover to the EFI partition?

    • I think I see the problem. Step 5 needs to come before Step 4. You are essentially telling me to install Clover to a partition then with Step 5 the command deletes my entire USB and only installs the Yosemite App leaving my Clover files deleted.

      • No. Not even close. The USB is not wiped at all nor are any of the sub partitions touched. Apples USB creator simply restores the App to the Clover Partition. You would need to understand partition layouts. This is why Cloning software is useless.

        Sometimes on the end user system (your system) the Clover files become hidden on the EFI partition. If you simply run the installer on it again you will see that the check box show up again. Please follow the guide as stated.

  185. Hi!

    That’s strange, when I run the command file, I have to change the permissions so I can run it. But I got an error when running:

    -bash: /Users/florianlecoq/Downloads/Clover 10.10.command: cannot execute binary file

    I’m on a MBP, OSX 10.10.3 !


  186. Hello !

    Thank you for this tutorial !

    For post install I need to know, with your tutorial, can I use “Trim Enabler” ?
    Your tutorial disable the kext signing security setting with kext-dev-mode=1 ?

  187. Acer gateway NE56R, core 2 duo

  188. I have a x79 Hackintosh running 10.9.5

    I also have a RAID 5 array through a Rocket RAID 2720SGL, essentially separate from the boot drive.

    If i do a clean install of 10.10, will the raid be corrupted or deleted in any way?

  189. Hi. Looking to be clear on some things before I start.

    On the UEFI Clover install method after you replace the config.plist file it says to navigate to the /EFI/CLOVER/kexts folder. There I am to open up the folder of MacOSX that is on the clover usb. It says to “Copy the Kexts into that folder.”

    My question is what kexts? How am I to know which kexts to put there?

    My second question is if it’s ok to install with this guide if I’m not using a video card and using onboard graphics? (HD4600)

    I’ll be using

  191. What I did was unplug the card and plug it back in. This stopped the flashing during the install. Have Yosemite installed and am moving to post install process. No issues when booting to HD but haven’t tested anything yet.

    Your tutorial here is excellent. My install so far has gone by the book really only a couple things that got me off track (install hanging with one second left for 5 or so minutes).

  192. Once again great job on tutorial. Gone through post install and OS X is stable. My build Asus x99 Deluxe and 5820k.

    I was able to install 10.10. However, I can only boot with -x option. Without -x, I got kernel panic. I’ve tried other options like npci=2000, etc but no luck.
    Is p67 motherboard supported by 10.10?

  194. I have an interesting issue I have a duel boot system, Win8 and OSX – when i restert from Win8 to boot into mac it shuts my whole network down. Any advice?

  195. Hi Andrew,

    Thanks for your excellent guide. I have used it to install Yosemite 10.10.3 on the following system.

    Asus Sabertooth z97 MK2
    I7 4790K
    32GB Ram
    250GB Samsung 850 EVO SSD
    Galax Nvidia GTX980 SOC
    Philips BDM4065 4K Monitor.

    Install went fine and with CSM off in bios install booted at 4K. I installed Clover on SSD along with config.plist, kexts and Nvidia SSDT for my motherboard from your Haswell.DMG. Downloaded and installed Nvida web drivers Version 346.0102f04.

    I have added -v nvda_drv=1 to Clover config.plist but it reboots when login screen should load. I can boot with -x and the GTX980 is correctly reported in “about this mac” and “system overview” I get full res 4K display but the Nvidia panel in system preferences won’t load, I guess due to safe boot. Also boots fine with nv_disable but low res.

    Also Audio patch on Haswell.DMG returns “no codec found” also due to safe boot I assume ?

    Any help would be much appreciated.


    • Sounds like something was missed in regards to the GPU.

      As for the audio you missed a step in the DMG.

      Here is what you need to do. Slow down. Read each step. Don’t skim. If there is extra documentation in a folder, make sure to read the documentation.

      • Hi Andrew, Thanks for quick reply.

        Regarding the audio, I did replace all instances of HDEF with HDAU in the script, sorry I didn’t mention it. I assume this is the step you were referring to?

        I have uninstalled & reinstalled the Nvidia web driver several times?


        • Correct. But what you are telling me now contradicts what you said before so lets do this. Send me the script you edited as well as a IOREG via EMAIL. Then I will see what’s going on with this issue(s) and get you straightened out.

  196. I have working install. However I had installed java and it broke my sound. Any idea what may have caused this and is there a simple fix. Sound works perfectly in my install computer can sleep and wake and still works.When I installed java the sound worked on boot but if the system slept then no sound.

    • Java is not related to sound. Unrelated. There is a Sleep bug with AppleHDA 10.10.x and what you see is a perfect example.

      • I have read some about the bug. In examples I saw there was no ability to choose an output. I can still choose output just no sound. Is this similar? Didn’t happen until I did the install, and I was able to repeat it so thought there might be something happening. Is there a work around for the bug? Since examples I saw were different then what I was experiencing I wasn’t sure where to begin.

  197. Sleep is the bug. So that is what I would like to take care of.

  198. Hey Andrew, thanks for all your knowledge!! I’ve made a new fresh Clover setup with Yosemite 10.10.3 running serenely with not much problems with your install guide. I migrate from Chameleon /Mavericks

    ASUS R4G / 4820k / GTX660Ti

    Evenly i have some doubts and issues:

    1) Should i create a SSDT-1 for my 4820k ?? I’m planning to OC it…

    2) I have the same doubt about the GPU, I have a GTX660Ti working CUDA do I have to follow the NVIDIA graphic guide?

    3) Not working USB 3.0

    4) Not working front USB (rare.. I have to check my BIOS)

    Thank you very much! You’r an idol!

    • 1. There should be a 4.5 Ghz SSDT on the DMG for your CPU which supports up to 4.5 Ghz stepping.

      2. No.

      3. Might need either boot flags or the BETA USB kext for USB 3.0.

      4. IRQ issue.

      • 1. There is no a SSDT-1 for my CPU (4829k) in the X79 DMG modified on December 24,2014 recently downloaded form your site.

        2. Ok! I think is working full spec!

        3. Ok! I will try when my Backup is working. Is the “GenericUSBXHCI.kext” and i have to installed it with the Kext Helper b7? If i need bootflags, what bootflags I should need?

        4. Can you explain me more about IRQ issue? Can be fixed?


  199. 1. By mystake I’ve typed 4829k but the model is 4820k. Is strange that in the X79.dmg don’t exist the SSDT-1 for my CPU because the “DMG Read Me” talk about a 4820 SSDT-1 that don’t exist too. If exist, can you send me the SSDT-1 by mail? If not, can I create a SSDT-1 for my system using the SSDT creation guide?

    3. I’ve installed “GenericUSBXHCI.kext” with “Kext Helper b7” and my USB 3.0 remain out of order. Where I can find the “Kexts release notes for flags” you talk?

    4. Can be patched with an existing patch? Where i can find it? If not, what can i do?

    Thank you very much!!

    • 1. Generate a SSDT-1 using the Guide for both stock and 4.5 Ghz clock speed. Then email the files to me so that I can correct them. Then I will re-add them to the DMG.

      2. See Developers repository for release notes.

      3. Needs to be done in the DSDT.

      • 1. Great! Today i send you the files.
        2. USB 3 rear socket now working!!!
        3. My system is working with SSDT injection, can I add a DSDT in the EFI patch folder? Where can i found a working DSDT for my system? I don’t know anything about programming… I only know that on my last setup with the same hardware and Mavericks I had my front USB working Ok…

        • 1. Good.
          2. What flags did you end up using?
          3. Yes, 1 DSDT that is ONLY patched for the IRQ’s and 20 SSDT’s technically speaking. IRQ requirements changed under 10.10 thus users who never had this issue before now have this issue.

  200. 1. I’ve send you by mail an error log making the SSDT-1. “board-id [Mac-F221BEC8] not supported by Ivy Bridge – check SMBIOS data / use the -c option”

    2. Do not need flags, on the second restart the rear USB 3 start working.

    3.Do you have a DSDT with the IRQ patched working for me?


  201. Suddenly cannot boot!

    Rebooted today and clover loads to Apple with black background but nothing past that. Tried verbose mode and stops at RTC: Only sing

    FakeSMC: 5 keys exported by Clover EFI
    ACPI: sleep states S3 S4 S5
    RTC: Only sing

    My setup:
    Asus deluxe x99
    32 GB Ram
    500 GB Samsung EVO

  202. Asus x99 deluxe
    500 GB Samsung ssd
    32 GB Ram

    Got to the post install but system hangs on reboot. Rebooted without issue after installing kext. Boot process starts off good then grinds to a halt. Seems to hang on AWLDPeermanager halts at considerRebuildOfPrelinedKernel prebuild rebuild has expired.
    Starts to hang at

  203. At Step 6, EFI partition wasn’t mounted. Followed your instruction to mount EFI partition – easy, and I was successful. On the EFI partition, there was only an APPLE folder. I created CLOVER and put the downloaded config.plist there… but since there was no CLOVER folder made, there was no ‘kexts’ folder inside of that. Do I just make it? Or did something go awry? Up until this point, it was all easily followed.

  204. I see the steps for downloading the OS X dmg and then it goes to the formatting the usb drive but skips to the Clover install without the showing of how to get OS X onto the usb drive. How is it that you get OS X onto the drive? Does installing Clover boot loader do that, or would you do it with the “restore” tab in the Disk Utility? Thanks

    • Please READ and follow the Guide.

      • I read the guide and followed it to a “T” but when I reboot and clover boot loader comes up, the USB installer of OS X doesn’t show up. Only the existing hard drives and if I removed those and leave only the one I want to install to the clover boot loader is blank. I have re done it following the guide several time with the same result. What could cause that?

        • Your skipping a step and not doing as stated in the Guide. That is the only cause for this and I am almost sure I know what you are skipping. So that said please READ and follow the Guide and make sure that you don’t assume you did something.

  205. Hey Andrew:

    I’m trying to install 10.10
    x79 deluxe
    geforce gtx 680 classified

    I make it all the way to part 10 and then during the install it reaches 0 seconds and a short while later shows

    Then reboots back to the clover screen. I’ve updated the bios and used -v cpus=1 npci=0x2000 kext-dev-mode=1 nv_disable=1

    What am I missing?

  206. System:
    Rampage IV BE
    Intel Core i7-3820
    4x8GB Crucial Ballistix Sport XT RAM
    EVGA NVIDIA Geforce GTS 450

    I followed your instructions and successfully installed Yosemite with ethernet working. However I noticed that the USB 2.0 ports on my motherboard are not working, and the auxiliary USB ports on the front will frequently disconnect all devices (external HD, soundcard, etc.) but the mouse and keyboard. Have you run into this problem before?

    Can you also recommend me a highly compatible ~$200 Geforce card within the 6 to 9 series range for video editing/compositing work?

  207. I have a problem im stuck in PCI CONFIGURATION BEGIN.

    my pc specs
    Intel i7 5960x
    Gigabyte x99-UD4
    16GB Ram

    i used bootflag
    -v kext-dev-mode=1 npci=0x2000
    -v kext-dev-mode=1
    -v kext-dev-mode=1 nv_disable=1
    still stuck in PCI configuration begin

    how to fix this? Thanks! !

    • Please READ. Do not SKIM. Please READ the beginning of the Guide.

      There is the fix for your issue if you READ the Guide. If you do this you will see how to fix this. 🙂

  208. Setup:
    Asus Sabretooth X99
    Asus Strix 970

    Following the guide,
    booting with 2011-3 flags.
    Stuck on this:

    Added x99 kexts from the DMG. Thanks for any help!

  209. I have installed Yosemite on my Lenovo B40 by same method… After installation, it seems touch pad is not working, and it is asking to add Bluetooth keyboard… I think its stuck in desktop mode…. Please help.

  210. i am having this issue i get the usb ready to go, have my bios csm disabled and the and the the secure boot to others, but when i try to boot the usb when it get half way it won’t continue i get an decline sign i can’t even see any error here is a picture of the problem, i have a rampage iv extreme, 3930k and a 780ti

  211. Question for Ivy Bridge:
    There is no config.plist in the download.
    Is there a recommended config.plist?

    (for a GA-B75M-D3P)

  212. Dear Andrew:
    Thank you for building this web site.
    I followed the simple steps, and made the system work.
    However, no matter what kind of application I installed, the system won’t be able to restart. It shows the sign of “No Enter” in the beginning black screen.
    The only thing I can install in the system is driver of NVidia …..
    My spec is :
    Asus Rampage Black Edition
    Intel Xeon 2680 V2
    NVidia GTX 750 SC
    in OSX 10.10.3

    Please advice.
    Thank you very much.

  213. Hello Andrew,
    Thanks soo much for your guides.

    I’m having a bit of a weird problem,
    My system is:
    Asus Z97-A
    8Gb Corsair 1600mhz DDR3
    I5 4670K
    Intel 4600
    Yosemite 10.10.4

    I had a Multibeast instalation, but the sleep/wake/shutdown wasn’t working after many tries.
    So i tried your guide and it worked flawlessly expect for the audio. I was trying to fix it but i screwed something up and the instalation didn’t boot anymore.
    So i cleaned up the SSD, and tried a new instalation (was going to make a image backup) before doing the post instalation.
    The weird problem starts now, first instalation apparently is ok, it reboots and the second part is the same as the first.
    It seems it doesn’t complete the first one 100%.

    I didn’t tried yet to do the spacebar and “boot without caches” in the clover bootloader, don’t know if it will help.
    I’m almost giving up, and going for the legacy instalation and then swap for the uefi one.


  214. Hi Andrew!

    I had sucsefully installed the Yosemite on my hackintosh, really thanks (it was 6 month ago).
    Now I’m trying to install Mavericks also, but I got this message: “DRMStatus: iTunes/Apple Store Content Access Problem. Content playback may be disabled on this computer. You can Continue to use the machine, but you should contact an Apple support representative. ErrorCode: 8877652”

    What should I do?

  215. Hello Andrew! Do you think a x99 system wil work with xeon 14core cpu?

  216. I am trying to dual boot into windows (which is a RAID – 0 Drive) , I installed ntfs.efi onto the EFI mount so I could better see the partitions. Now when viewing the windows I see boot windows on “” , Assuming thats some kind of weird issue.

    Regardless it fails to boot into the RAID just comes up with a graphic of an X in the middle . Any ideas?

    • I fixed by doing
      – Setting My Clover boot in the first , My Windows in the 2nd boot sequence.
      In my config.plist set Boot/Legacy=LegacyBiosDefault

      And instantly it started to work!

  217. First, thanks for the very helpful resource.

    Second, I have one question: I have an X99 machine here (ASUS X-99 Deluxe/5930k), and in order to install Yosemite, I need to:

    1. Install Yosemite onto a disk attached to a Real Macintosh ™;
    2. reboot into that version of Yosemite;
    3. do the post-install DMG work;
    4. power the machine off and install the drive into my Hackintosh;
    5. continue on with the guide

    , correct? Thanks in advance.

    • Nope. You do not have a 8 core so you can install by following this guide. 🙂 Enjoy.

      • Cool, good to know. I wasn’t having much luck with the guide — I couldn’t get the system to boot far enough to run the install, so I just punted and — given a functioning X99 machine, and my Mac Mini — did the following:

        0. Updated the ASUS BIOS to the latest version (18mumble);
        1. Installed my target SSD into a Thunderbolt enclosure;
        2. installed vanilla Yosemite 10.10.5 onto the disk;
        3. mounted the EFI partition from the SSD, and performed Steps 1-3 from the X99 DMG guide;
        4. invoked the magic perl s// command on /Volumes/SSD/System/Library/Kernels/kernel
        5. removed the SSD from the Thunderbolt enclosure and installed it into the Hackintosh;
        6. booted up, selected the SSD from the ASUS boot menu, and then set boot flags in Clover, which got me to
        7. a Yosemite install, in safe mode, on my Hackintosh!

        I was then able to install the nVidia web drivers, modify the clover plist to add “nvda_drv=1”, and restore my system from a Time Machine backup.

        What’s working with no other hacking: WiFi, USB 3.0, USB audio. What isn’t: Bluetooth, and, weirdly, the video drivers keep getting set back to “OS X Default Graphics Driver”. Tomorrow I’ll run some CUDA codes to see if the video cards are being recognized, but overall, this was really, really seamless.

        Kudos to Andrew and all at Rampage Dev who made this so easy.

  218. Hello,I have an Asus Maximus VII formula, how do I get a SSDT for it?
    I install Yosemite with Clover , i don’t get sound working. There is any solution for this?

    Thank you!

  219. thanks for the detail steps.
    unfortunatelly, I failed to install it successfully, stuck with “Legacy usb off done” and reboot~~~
    My computer info:
    – Intel DX79SI board with i7-3960x 16G memory
    – Intel 520 SSD, plus Hard disks
    – Windows 7 ultimate 64bit

    If anyone can kindly assist, I’ll provide more details soon 🙂 thanks~

    • Can you post a picture? Thank you.

      • Hi Andrew, thank you so much for the reply.
        somhow I lost the screen shot days ago 🙁
        when I have next try, I’ll record down the details and seek for help again.

      • Hi Andrew, I finally followed every steps and installed the Yosemite 10.10.5 to my computer, I removed the HD containts Windows system and used an empty SSD to install it.
        To make others can take as reference, put some details here:
        Computer info: Intel DX79SI board with Intel82574L & Intel82579LM NIC, NVIDIA GeForce GT630, Intel 240G SSD, i7 3960x, 16G mem
        Clover boot flags: -f -v cpus=1 npci=0x2000 kext_dev_mode=1 nv_disable=1
        Status quo:
        – still need to boot into Yosemite with the USB disk, with boot flags: -f -v cpus=1 npci=0x2000 kext_dev_mode=1 nv_disable=1
        – Intel82574L still not OK, so that all the post install steps in X79.dmg can’t be executed yet.
        – did something wrong maybe, can’t login to Yosemite, need re-install perhaps
        Next steps:
        – I’ll reinstall the system again
        – make the Intel82574L driver OK.
        – do the steps in X79.dmg and try to make UEFI boot ok, GeForce GT630 and audio card OK.
        Hope that I can make it~~~
        thanks again!

        • GT 630 needs Nvidia inject to equal true.

        • (Intel DX79SI, NVIDIA GT630,i7-3960x)
          finally got Yosemite up & running, with the following changes in config.plist:
          1. didn’t apply the DSDT.aml in DX79.dmg step3, just left \EFI\CLOVER\ACPI\patched folder empty
          2. used Clover Config tool to modify the config.plist
          ACPI part: FixHDA, FixUSB, FixSATA, NewWay, FIX_RTC, FIX_TMR, AddIMEI, FIX_INTELGFX, DeleteUnused, Patch APIC, Halt Enabler
          3. boot part (boot parameters)
          -v -cpus=1 npci=0x2000 kext-dev-mode=1
          4. Graphics part for NVdia GT630
          Load VBios, Inject EDID, Inject NVidia, Nvidiageneric
          also, put customer EDID for my monitor
          5. Kernel and Kext Patches part
          Kernel CPU, Kernel LAPIC, KernelPm, Apple RTC, Asus AICPUPM
          (the Asus AICPUPM may should not apply; also I didn’t apply KernelHaswellIE because my cpu is SandyBridge cpus)
          6. SMBIOS use MacPro5,1
          7. System Parameters part
          Inject System ID
          besides all the configuration above, I also used xxxxxx to apply the following drivers:
          a. for Audio part: ALC892 sound card, installed VoodooHDA v2.9.7 instead (the ALC892 driver not worked well)
          For NVidia GT630, I found the drivers from internet.
          Now it works!~~~~ (sometimes unstable, after logged in, the screen will become ‘white screen’ or stuck on other color screen)

          Thanks a lot~

        • Hi Andrew, one question regarding the cpus=1, does it mean only one core of the cpu will up and running? thanks~

        • Yes. This is only for installation.

  220. Hello, i install Yosemite with Clover on asus maximus VII Formula i7-4790k@4.00GHz. For some reason i don’t have sound. There is a way to fix this?
    Do i need SSDT? if yes can i get guide on this?

    Thank you!

  221. I’m trying to install 10.10.5 on the following hardware:

    Intel 3930k (stock or 4.5 OC, same result)
    Asus P9X79 Deluxe (Latest BIOS as of 9/9/2015)
    4×4 2133 RAM (XMP on/off, same result)

    Tags used:

    -v kext-dev-mode=1 GraphicsEnabler=No cpus=1 npci=0x2000 PCIRootUID=1 nv_disable=1
    I get to the grey screen, get ~5% of the bar loaded + Beach ball, after that all my USB devices shut off

    -v kext-dev-mode=1 GraphicsEnabler=No cpus=1 npci=0x2000 PCIRootUID=1 nvda_drv=1
    I get to the grey screen, instant beach ball, after that all my USB devices shut off

    Any ideas?

    I have had OS X installed before, but unfortunately I do not remember how i did it.

    • Failed to use the flags listed in the Guide. Please follow the guide as shown and not what you find on Google. The flags listed here can and will work for your configuration and i can not state this enough that failure to do so will result in failure to get anywhere in the install process.

      • Fixed that by disabling Bluetooth in BIOS (not needed anyways) + apparently the motherboard does not save CSM settings, had to re-do them every time i boot.

        In any case, sorry for my ignorance the first time. I was pretty salty about not being able to boot for 4 days, tried a ton of methods, but your’s ended up working flawlessly.

        Got 10.10.5 running flawlessly now

  222. Hi ! I always have the same issue and ill show you in the following link, but first, my config :

    Gigabyte gaz97x-sli
    Intel i7-4790k
    Gigabyte gtx970

    And the issue :

    And after 1minute : a text on the left side : Still waiting for root device

    Please help me sir

  223. Andrew,

    Thank you for providing this service! I have been reading your guides and your responses, so I believe I have meticulously followed your guide to a tee!

    I am trying to install a Clover booted Mac OS X Yosemite 10.10.5 on the following system:

    Mobo: Gigabyte GA-Z97X-UD7 TH
    Processor: Intel i7-4790K LGA1150 (I believe this is called the “Haswell”)
    Memory: 32GB Crucial Ballistix Tactical DDR3 1600
    Graphics: Onboard Integrated (Intel HD 4600 I think it is)

    When using your Mac OS X Install Guide, I cannot seem to make it to Part 8, Step 6, (Booting the OS X Installer).

    When I do this I get this (Stuck on DSMOS has arrived):

    In case it matters, here is what I am trying to do. If this is impossible, or if there is a better order or way to do this, please let me know:
    1. I want to get a Clover booted OS X 10.10.5 system running with the Onboard graphics.
    2. Then I want to install an AMD Vapor-X R9 280x graphics card that I have after that.
    3. My desire is to use both this discreet graphics card and the onboard graphics simultaneously.

    Thanks for your assistance!
