snitz Posted April 30, 2014 Share Posted April 30, 2014 I have a PC with ASROCK G41C-GS, Core2duo E6600 and Geforce9400GT on PCI-E had installed Mavericks 10.9.2 working perfect with QE/CI ps. dual boot with win7 Few days before I purchased a Xeon X5460 of LGA771 and used some mods to install it on by 775 mobo. After the installation, win7 starts fine and recognise the cpu correctly. But once i boot into mac, after the apple loading wheel screen, i just see a black screen with some color palettes. Sound volume control works so I think the os is running, just the display is completely broken. I managed to switch the display to onboard GMA4500 that successfully boot into MACOS but with no QE/CI As the Geforce card was functioning before the cpu upgrade, I guess maybe something related to PCI-E is change with the different CPU type. Any clues on how to fix this? Thanks. Quote Link to comment Share on other sites More sharing options...
iFIRE Posted April 30, 2014 Share Posted April 30, 2014 the GMA4500 not have full support in Mac OS can be this your problem, go to the bios and put en off your GMA and seletc your PCI CARD NVDA in the first place to boot, then try delete all ATI* IntellHD* AMD*, repair permissions with Kext Wizard/reboot , if not solve your problem try a clean install.
