My Macbook Pro has been flashing MAJOR graphics artifacts since upgrading to 10.8.3 (this did not happen in 10.8.2). When the glitches become severe enough, the system freezes up completely, with a hard restart being the only recovery.

I'm hoping that 10.8.4 will fix this issue!

Here are some videos of my problem:

Re: This shutdown bug.

Can I ask why, in this day and age, why on earth people are doing it so often?!?

My macs never get restarted apart from Software updates or rebooting into Windows. MBP hasn't been restarted in 30 days and MP two weeks!!

If it is done on purpose (which it is) then it isn't a bug...

Because we masturbate to watching our macbooks restart.

Why the hell do people keep asking this? It's a bug and it should be fixed that's all.

Then who do you blame?

I don't blame anyone. I like Mountain Lion. I think Lion could've used more polish before release, but I think Mountain Lion was a return to form. I have very few complaints about 10.8.

They really seem to be taking their time with this one. I hope the get most of the crap ironed out. OS X gets buggier and buggier with each new release.
