  1. Hi Andrew,
    And about cpu name in yosemite with 5960x, do you have a solution?

  2. Thank you Andrew. tried it today, works perfect.
    Had another issue, that OSX not kept the desktop background pictures set after next reboot, if they were not located on Boot Volume.
    So here I found a simple fix, that allows OS X to mount volumes before User login:

    sudo defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin true

    maybe this is of value
