In the default installation of your Hackintosh, SpeedStep is disabled because of the NullCPUPowerManagement.kext that is installed. There is however a way to get SpeedStep back, if you wish to have it. I’ve tested this myself and it doesn’t affect the rest of your system (or how NullCPUPowerManagement.kext/Disabler.kext function). Just copy the VoodooPowerMini.kext to /System/Library/Extensions/ on Macintosh, repair permissions and reboot. To check its working correctly, you could use boot flags “-v” (without quotes) and check for output mentioning SpeedStep management.
Follow these steps:
- Download the kernel extension. (VoodooPowerMini.kext)
- Copy and paste the extension to /System/Library/Extensions/
- Run the following commands in Terminal.app:
sudo -s chown -R root:wheel /System/Library/Extensions chmod -R 755 /System/Library/Extensions touch /System/Library/Extensions diskutil repairPermissions /System/Library/Extensions
You can now reboot. SpeedStep should be enabled on your next boot.
