xinjia Posted July 14, 2012 Share Posted July 14, 2012 I've solved it by putting the Lion's Extra folder in ML Link to comment Share on other sites More sharing options...

rcork Posted July 14, 2012 Share Posted July 14, 2012 I had a similar issue and after i knew it had booted to the install screen (but i couldn't see anything), i pushed the power button on my hack to put it to sleep. Then i woke it up and the screen showed up and i could proceed with the install. Link to comment Share on other sites More sharing options...
Sharon Posted July 14, 2012 Share Posted July 14, 2012 I got it working finally. I deleted following kexts , I did the deletion manually of those kexts and it boots into installation. Installing now...... rm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/AppleIntelGMA* rm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/AppleIntelHD3000*rm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/AppleIntelHDGraphics*rm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/AppleIntelSNBGraphicsFB.kextrm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/AppleIntelIntegratedFramebuffer.kextrm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/AppleIntelSNBVA.bundlerm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/ATI*rm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/GeForce*rm -rf /Volumes/Macintosh\ HD/System/Library/Extensions/NVDANV* Link to comment Share on other sites More sharing options...
napster-grey Posted July 14, 2012 Share Posted July 14, 2012 Thanks so much Sharon, I deleted the kexts u mentioned plus 2 additional ones and it works, without any parameters like GraphicsEnabler: /System/Library/Extensions/AppleIntelGMA* /System/Library/Extensions/AppleIntelHD3000* /System/Library/Extensions/AppleIntelHDGraphics* /System/Library/Extensions/AppleIntelSNBGraphicsFB.kext /System/Library/Extensions/AppleIntelIntegratedFramebuffer.kext /System/Library/Extensions/AppleIntelSNBVA.bundle /System/Library/Extensions/ATI* /System/Library/Extensions/GeForce* /System/Library/Extensions/NVDANV* /System/Library/Extensions/NVDAGF100Hal* /System/Library/Extensions/NVDAGK100Hal* Now I got it installed but the only possible resolution ist 1280x1024, with NVDAGF100Hal.kext it keeps crashing after loading the kexts... + Can't even boot to single user anymore Link to comment Share on other sites More sharing options...
