Notes / Suggestions

  • Keep your installation USB on hand. After installing Mac OS system updates it is sometimes necessary to boot the system with the USB and re-install kexts to get everything working properly again.
  • Use Clover Configurator if you need to mount the EFI partition or make modifications to the provided config.plist
  • If a kernel panic occurs, boot from the installation USB, select the installation drive, hit the space bar and select Boot Mac OS X in safe mode to successfully boot and make necessary changes.
  • Recommended OS X compatible half-height Mini PCIe wifi cards that require no configuration and are automatically recognized as built-in AirPort: Dell DW1515 or Dell DW1510
    A good list of additional Mini PCIe wifi cards compatible with OS X is available here
  • The <ScrLk> key decreases screen brightness, the <Pause> key increases screen brightness
  • The <PrtSc> key toggles the touchpad on and off
  • If the Bluetooth radio is turned off in Windows it may no longer show up when booting into OS X. Boot back into Windows to turn the Bluetooth radio back on.
  • Fan noise can be reduced by changing the BIOS setting under Config > Power > Adaptive Thermal Management to Balanced

Not functioning

  • USB ports after resuming from sleep
