As always its running in clamshell mode hooked up to a 30" ACD. After the required restart I got a kernel panic before the OS fully loaded. I powered down and could not get it to restart past a faint grey screen. There was no spinning wheel or ball. I unplugged it from everything and rebooted and it finally booted but I'm wondering what happened. The only updates I allowed was for my airport and some security update. I'm still running tiger 10.4.11. The only thing new was a pair of speakers. Oh and it is 4 days out of Apple Care. Edit: Now I'm all plugged back in and running ok. Some odd behavior that ultimately led to reboot and then discovering the new software update push, was while downloading from iTunes or using the internet at all, my mouse would stall. I am on a wifi connection but the connection is 6" from my powerbook so the signal is strong.
