A few days ago, I told my 15" i7 MBP to turn off from the apple menu. It didn't shut down properly, and this message popped up telling me to hold down the power button until the computer turned off. I thought this was weird, but didn't think too much of it. Then, a couple days later, on the mac, I accidentally forgot to eject an external hard drive (NTFS) before turning off the firewire device it was daisy-chained to from the mac, which erased the partition table, leaving the drive unreadable on both OSX and Windows. Then today, I was in Safari, and I noticed that when I open a new tab, all of the small windows that show my top sites have completely garbled graphics. This is annoying but I didn't restart Safari. Well, eventually, I open a new tab and page, and the entire page has garbled graphics. Then the computer completely freezes and I get the same message saying "You need to turn off your computer by holding the power button..." Here is a screenshot: I'm currently doing data recovery on my external hard drive, and maybe these issues are all unrelated, but has anyone seen garbled graphics in Safari like this? The only thing I can think of is I had gfxCardStatus running and locked on Intel graphics What the heck is going on?
