Sure I've had the odd program (VLC) take up the whole screen and die, so I couldn't kill the app to get back to the desktop, but the system was always extremely stable under Mac OS X Tiger.
Last night my MacBook under Leopard crashed. O_O
I was actually, shocked. Like, jaw on the floor shocked. I actually didn't know what to do. LOL Sure I've seen Windows BSOD (blue screen of death) and Vista BSODs, but I've never seen a Mac OS X kernel panic before.
It actually sounds worse then it is, the screen just shows up with a big power icon and tells you to reboot the system.
So the work around seems to be disabling IPv6 in Airport and so far it's been stable after that. It ran fine overnight and hopefully will continue to do so when I go home tonight. It's funny, I specifically waited for Leopard to come out with an update (10.5.0 -> 10.5.1) before buying it. You know, typical Windows user, never buy the first version, always wait for the first service pack.
It seems that Tiger users are having the same problem after installing the latest software update. It seems related to the new Airport drivers for Tiger and Leopard.
So if you guys haven't upgraded yet to the latest version of Tiger (10.4.10) or Leopard (10.5.1), you might want to skip it.
On the plus side, Time Machine, Quick Look and Spaces has been awesome!
Oh and on a TOTALLY UNRELATED NOTE! Working on memorizing the lyrics to You Can't Stop The Beat from Hairspray. O:)
And this chunk always seems to throw me
Ever since this old world beganI think all the S's are throwing me... X-D
A woman found out if she shook it
She could shake up a man
And so i'm gonna shake and shimmy it
The best that i can today
