So what should you know before I begin?

  1. Always ask us before you buy a Dual CPU board if the board will work for Mac OS X. Many of the offerings on the market simply do not work or require so many work arounds that they are unstable.
  2. Yes, you can update from the Apple App Store. We have tested Mac OS X 10.11.3 to 10.11.4 to 10.11.5 however you must install NULLCPU (provided on the DMG) prior to updating or the system will not be able to boot.
  3. Yes, you can do a clean install using our Installation DMG and expect the system to take 15-20 mins to boot to the install screen.
  4. Do not install Black Magic Cards in slots that are on the same CPU as a GPU. There is a open issue with their driver that floods the PCIe lane which bogs down GPU performance.
  5. Last the Clover Config file is hardcoded for 128 GB of ram. If you install more then 64 GB of ram you must hard coded the amount in the Clover Config list.
