Hello people,
I've installed Mavericks on my AB9-Pro with a PNY GT430, and all went well.
The OS will start and work fine, but on reboot the AppleIntelCPUPowerManagement kext fails as no HPETs are available.
If I boot to my 10.6.8 drive and run the multifail system utils to update caches and repair permissions it will boot again, but only once.
Anyone having similar problems or found a fix?
