Hey everyone, I just picked up my Retina Macbook Pro less than a month ago and I'm already getting a problem with it. I updated to the latest 10.8.1 Mountain Lion update yesterday and my computer was performing regularly after. I then turned it off and tried turning it on again after it had been powered off for about 3 hours but it was stuck at the screen with the Apple logo. I'm able to adjust the brightness, volume, and things on that screen but I have a rainbow circle and my computer just isn't turning on. I've booted it into recovery mode and repairing the hard drive and its permissions but it doesn't help. Does anyone have this problem? Any solutions? PS: Can it be related to the fact that the computer, when I first bought it, was re-imaged through my school to have Adobe CS5, MS Office, etc.? Usually they only use that image on 13" Pro's but I was an exception.
