MacBook Air 13-inch, Mid 2012

Connected to an external monitor via Micro-DVI-to-DVI adapter


Updated to Mountain Lion this morning. Applied SMC Update with a restart, and got stuck at Apple logo. The external monitor displays a very light grey (dark white).


Forcing a shutdown (by holding down the Power key) and restarting without an external monitor enters OS X normally. Power Nap is available in System Preferences > Energy Saver.


Problem is consistently reproduced when restarting or starting with an external monitor plugged in. Restarts and startups are fine without a monitor attached. I can successfully connect the external display after the system's up and running.


Anyone run into this problem?
