Hi guys I have same problem. Computer has following HW: MSI H81M-P33 Intel Core i3 4330 with Intel HD Graphics 4600 ZEPPELIN 4GB DDR3 1600MHz GOLD Before installation and after installation I had to go this: boot with -s Type: mount -uw / Type: cd /System/Library/Extensions Type: mkdir intel_back Type: mv AppleIntelHD* AppleIntelF* intel_back/ Type: touch ../Extensions reboot with -v GraphicsEnabler=Yes IPGEnabler=Yes PCIRootUID=1 If I wouldn't do that my Mac couldn't even start (after installation I can start just with -x mode if I wouldn't do that). But I have Intel HD Graphics 4600 and it show to me 7MB VRAM of Graphics, and no kext loaded (of course they are moved) but Ican't start with these files in the folder. So.. what should I do? Edit: I found out that boot working with every file of this name but exclude AppleIntelFramebufferAzul.kext. This kext doesn't work and doesn't let me boot.
