I have seen similar issues to what I am experiencing in this thread: http://social.technet.microsoft.com/Forums/en-US/mdt/thread/1036deca-bd04-4fe2-aaec-2c17bb86a63f/ but I wanted to start a new one specific to this issue.
We were running MDT 2012 fine. After upgrading to MDT 2012 Update 1 (Even the newest one) our Dual Boot Mac installs get to the end of the first step where it applies the image, reboots and then sits at a blinking cursor. I have tried everything including adding ACTIVE to my custom format - All with no luck. I have even created a second server and tried a brand new install all with the same result. PC's work fine and use the EXACT same image. Attached are the log files or at least a portion of them...
