WhizZz Posted February 13, 2013 Share Posted February 13, 2013 Today I tried to upgrade Snow Leopard to Mountain Lion but I have some troubles with it: I have 3 partitions: Windows 7, Snow Leopard and MyHack OS X Install Disk (Can't find any USB stick with a storage of 8Gb). If I boot up my pc and choose my install partition for Mountain Lion, first the Apple logo shows up (if I use the flag -v it stuck at "pci configuration begin") and after a while my screen tells me "No input". PC specs: 4GB Ram NVIDIA GeForce GT 230 Intel® Core Duo CPU E7400 @ 2.80GHz Do I something wrong or did I forget something? Kind Regards, WhizZz Quote Link to comment https://www.insanelymac.com/forum/topic/286349-myhack-cant-install-mountain-lion-black-screen/ Share on other sites More sharing options...

Gringo Vermelho Posted February 13, 2013 Share Posted February 13, 2013 Remove SleepEnabler.kext or boot with the appropriate PMVersion= flag. Use the search to find more information, I don't remember how it works, I've never used SleepEnabler. 1 Quote Link to comment https://www.insanelymac.com/forum/topic/286349-myhack-cant-install-mountain-lion-black-screen/#findComment-1888698 Share on other sites More sharing options...
