    I had been running 10.7 since it came out without a single issue. After installing 10.8 on my 2011 MBP quad core I'm having a bad issue with it. Basically the computer will sleep and not wake. Sometimes I get a gray message saying that your computer had to be restarted for some reason. Other times I have to do a hard reset on it. It's gotten progressively worse in the last couple of days. Any idea what could be wrong or how to fix it?

    It was a clean install with a re-formatted hard disk.

    I *believe* this has something to do with the same problem some of us have been having with bootups going to a black screen.

    There is a thread on this here already in this forum area.

    We think it's a graphic driver issue introduced with Mountain Lion.

    Please do two things...

    Call Apple Care so they know the problem exists.

    Go to apple.com/feedback and let them know the problem exists.

    The more people that report this issue the faster a firmware fix can be issued.

    I had a issue similar to this. After upgrading to ML my rMBP would wake from sleep to the login screen but once I typed in the password it just booted to a black screen. I panicked but then remembered the recovery partition. I booted into it, fired up disk utility, verified and repaired permissions and then all was well. Might want to give it a try. Good luck!

    Thanks for the tip. I can try that.

    How do I boot into recovery mode?

    Also, realize, this problem happens randomly and not very often -- at least for me. I get the black bootup screen every couple of days.

    Hold the option key while booting up the machine. You should see several different options. The two default would be your Macintosh HD (which is your normal partition) and a "recovery" drive. Double click the recovery and you will see several options one of them will be disk utility.

    Sugared,

    Thank you again for the assistance.

    Was able to boot into recovery and run Disk Utility Verify and Repair.

    No indication anything was wrong, but I ran the repairs anyway.

    Still think this is a graphic driver issue related to Mountain Lion.

    We'll see if your fix does anything in the meantime.
