Article: UniBeast 3.0 Update
same as many other GB users, just logo to black screen.... tried graphicsenabler=yes with no success, ideas?
"PCIRootUID=1 GraphicsEnabler=Yes" got me to the installer. Worth a try.
I then found my mouse and keyboard we're working so booted back into Mountain Lion, opened Terminal and revealed hidden files by typing: "defaults write com.apple.Finder AppleShowAllFiles TRUE"
I then copied my current functional DSDT from System > Extra folder to the USB drive Extras folder. Mouse and keyboard now work fine now during installation. Still needed to type "PCIRootUID=1 GraphicsEnabler=Yes" at boot menu to get into installer.
Thanks to all those who've posted similar findings without whom I never would have worked this out!
