Sadly, my MacBook just crashed. It pissed me off quite a bit, and the screen didn't even turn blue. This is actually the first non-processor freeze crash that I've ever experienced on a mac. Actually, I think I may have seen a similar thing happen about 11 years ago, and I had a debugger that would run whenever it crashed. I believe the debugger actually caused it to crash more often than it would have otherwise.
Anyhow, they kindly tell you in several languages on a grey background that you need to restart.
I'm thinking that this may have something to do with Firefox, as I had that running for about 36 hours straight. So it might not really be their fault, but I don't think I'll cut them slack. It's not supposed to let itself crash no matter what.
I've read that the current OS update is rife with similar crashes, but this is the first time I've experienced it.
Oh, and I'm using GOOD to refer to the Grey Overlay Of Death, akin to the BSOD that NT and beyond will throw at the unwitting user from time to time.
