tinkythomas Posted May 27, 2013 Share Posted May 27, 2013 Hi, I have successfully installed ML 10.8.3 on my PC. I have had several issues but have managed to resolve all but one! The problem is with resuming from sleep. Everything works as expected but display is black with the exception of a small area (top left). This area of the display is also garbled (pixelated) which is probably the best description I can give! I have to reboot to restore to full display. The system specs are as follows... Case:Silverstone SG03 SFF MB:Asus Rampage Gene II (Latest BIOS) CPU:Intel i7 920 D0 RAM:Corsair Dominator 6GB DDR3 CPU Cooler:Corsair H50 water cooler GPU:HIS Radeon HD5670 OS:ML 10.8.3 with DSDT Hope someone can help me?

tinkythomas Posted May 28, 2013 Author Share Posted May 28, 2013 Wonder if this could be an issue with AppleGraphicsPowerManagement.kext? I will check the Info.plist for Vendor/Device ID for my card. Probably clutching at straws here but it's worth a shot!? Link to comment Share on other sites More sharing options...
tinkythomas Posted May 28, 2013 Author Share Posted May 28, 2013 No luck with editing the kext! Really don't know what else to try? Any suggestions would be greatly appreciated. Regards, Chris Link to comment Share on other sites More sharing options...
