cybris Posted September 22, 2012 Share Posted September 22, 2012 My system as follows Motherboard: ASRock x79 extreme 3 CPU: intel i7 3280 sandy bridge Memory: 32 gig Video card: Nvidia 580GTX I've been able to create a bootable USB install drive. I have to boot with cpus=1 flag otherwise I get video lag with the GUI. I had to find some additional kexts to get the 580gtx to work. It works now. I am able to install ML to the HDD. However when rebooting after the install then picking the HDD. I get an unsupported CPU kernel panic. Anyone know what I am doing wrong? Link to comment Share on other sites More sharing options...
eep357 Posted September 23, 2012 Share Posted September 23, 2012 Install NullAppleIntelCPUPowerManagement.kext until you can enable native power management Link to comment Share on other sites More sharing options...
cybris Posted September 24, 2012 Author Share Posted September 24, 2012 I have nullcpupowermanagement.kext on the usb flash drive in the /s/l/e dir on my usb stick. I am able to boot from the usb stick fine but then when i select the HDD in chameleon boot loader that I installed ML on. It immediate KP's with the unsupported CPU error. I never get a command prompt to be able to install any kexts to the HDD. Link to comment Share on other sites More sharing options...
eep357 Posted September 24, 2012 Share Posted September 24, 2012 Install it from the USB stick, to your HD using terminal in the installer. So if for example your HD was called Macintosh HD.... cp -R /System/Library/Extensions/NullCPUPowerManagement.kext /Volumes/"Macintosh HD"/System/Library/Extensions/ Then reboot into HD using -f boot flag Link to comment Share on other sites More sharing options...

Nur710As Posted December 20, 2012 Share Posted December 20, 2012 No need VoodooTSCSync.kext?http://rampagedev.wo...nd-amdati-gpus/ there isn't about Asrock x79 Extreme 3. In my case Lion installed succesfull, but ML booting only with cpus=1. Link to comment Share on other sites More sharing options...
