I just got through a really rough crash on my new MBP. I had been creating an album in iPhoto, when I noticed it was really slow and was taking a long time to render the photos (as in i could see the low res thumbnail but the full res would take a while to wipe over it). So I quit iPhoto and reopened. The first thing I noticed was the dock became unresponsive, and then nothing was responding, the mouse cursor was still moving but i could not switch apps or anything. Force Quit window came up but very slowly, and then the mouse became ALMOST frozen as well, in that the cursor would only jump to a new position once every minute or so. This went on for about 10 minutes, then everything came back up and running for about a minute, during which I could switch apps and check my mail briefly, but then froze again. I pressed the power button briefly (not force shutdown), about a minute later, the shutdown dialog came up. I pressed enter to select shutdown, and another minute later the computer started to shutdown. So thankfully I got through all that without having to force shutdown. Unfortunately that wouldn't have been my first time forcing a shutdown. I've had a few rough crashes with this computer already, which is really disconcerting. I had one really intense graphics glitch at one point, where the screen was streaked with horizontal lines, and the image was squished and multiplied into three identical images side by side. I'm hoping that issue might have been addressed with the recent updates for 2011 MBPs that came out over the last week. I was hoping that would've been the end of scary crashes but it seems that's not the case for me. In general, I've found my computer to be disappointing in performance. This was an upgrade from a 2007 MBP that was replaced for the NVIDIA 8600m issues. I was wondering if the slowness might've been due to the fact that I did a restore from a time machine backup of my old computer. But I can't imagine a cluttered hard drive and a bunch of old apps causing issues like this!
