I've now experienced this issue three times.

It seems that activating Mission Control causes my MBP running Lion 10.7.3 to freeze, requiring a forced power-off and reboot.

MacBook Pro is a "Core i7" 2.8 15" Mid-2010 model (6,2)


Is anyone else experiencing this issue, or anything similar?

I'll try and paste the crash report here next time it happens...

MacBook Pro (15-inch Mid 2010), Mac OS X (10.7.3)

    I am having this same issue as well. I had my computer into the Apple store where I live for four days, but they could not recreate the problem. The last two times it has happened I noticed when I was going to use Mission Control (Which I have as a hot corner) and the compuer just locks up right as my cursor hits the corner and Mission Control starts. The screen goes black, if the keyboard is lit up it stays lit up, and the fans just keep running. The Computer is then completely unresponsive and I have to do a hard reset.

    I recommend updating to the latest Mac OS 10.7.4

    Upgrading to Lion 10.7.4 is likely _not_ going to fix the issue. See other threads,e.g. (; your best bet is to get Apple to replace the GPU logic board.

    In answer to your question: yes.
