Ahmadinijad Posted April 2, 2014 Share Posted April 2, 2014 This is my first go-round with the Hackintosh so please be patient of my ignorance. I have a gigabyte mobo, i5 processor with onboard graphics, also GTX650. I run DVI to Asus PB278Q. POST screen works, I can get into BIOS setup, then I get the grey Apple. It spins for a few seconds, then black. I try both DVI ports, -v and -x flags, GraphicsEnable=Yes and =No, and npic=0x2000. All same result. Also when I get the verbose output the last line before black screen is "WARNING: IOPlatformPluginUtil : getCPUIDInfo: this is an unknown CPU model [screenshot cuts off] -- power management may be incomplete or unsupportedSound assertion in AppleNDACodecGeneric at line 352" If I enable onboard graphics and set Initial Display Outpu to IGFX, will PCIe output still function?

iFIRE Posted April 2, 2014 Share Posted April 2, 2014 disable IGPU from BIOS, initial display PCIe, delete all AppleIntelHD graphics kext and AMD* ATI*, repairpermissions with Kext Wizard reboot to boot and make it try this flag: -x -f -v GraphicsEnabler=No npci=0x2000 dart=0 Link to comment https://www.insanelymac.com/forum/topic/297218-gtx650-black-screen-after-grey-apple/#findComment-2009269 Share on other sites More sharing options...
Ahmadinijad Posted April 2, 2014 Author Share Posted April 2, 2014 "disable IGPU from BIOS, initial display PCIe," This I have done. "delete all AppleIntelHD graphics kext and AMD* ATI*, repairpermissions with Kext Wizard" These things I do not know how to do. Can I do this from the boot option screen?

Ahmadinijad Posted April 4, 2014 Author Share Posted April 4, 2014 Still nothing. I'd like to try to make it work on the Intel graphics. Will this reverse the above changes? fsck -fymount -uw /cd /kext_backupmv AppleIntelHD* AppleIntelSNB* AppleIntelFramebuffer* AMDRadeon* ATI* /System/Library/Extensionsmkdir ../Caches/com.apple.kext.caches/Startup/kernelcachereboot Link to comment https://www.insanelymac.com/forum/topic/297218-gtx650-black-screen-after-grey-apple/#findComment-2009782 Share on other sites More sharing options...
