I am having trouble after updating to 10.8.4 from the combo updater. My computer was working great with full GFX acceleration (120 fps in Starcraft 2) while on 10.8.1. Upon upgrading to 10.8.4 I found myself unable to boot unless I was using -x at boot.
I have a GA-z77x-ud5h and a 2gb GTX 670 by EVGA with a Core i7-3000K. Any help would be appreciated. I also can't get the myHack installer to boot after using the 10.8.4 App Store update to create the installer if this offers any clues.
Thanks for the help.
