I have a new MBP retina and after the latest Mountain Lion updates which I seem to remember including an iPhoto and Aperture update but also seemed to "flash" the EFI? (not sure), but there seemed to be some OS update included. Either way, my first initial issue was that when I clicked on my user account and typed in password after boot, it took me to a dark gray screen and just stayed there. I finally was able to log into guest account and switch over to my desktop then fiddled with resolution settings and background and shut down applications and rebooted. I can now log into my main user account but I cannot shut down or restart from any account. It will take me to a white/gray screen and hang there perpetually until I hold down the power button.

 

I've tried resetting PRAM before and after removing all cables for 2 mins. The issue persists in both my main account and the guest account. The computer simply will not shutdown or restart as it takes me to a white screen.

 

Ideas?
