I'm a fairly recent mac user. Been using windows for decades and happily switched. But i upgraded from 10.6 to 10.6.1 last night and the upgrade looks like it failed.
I restarted the machine when it asked to then went to bed. In the morning the computer was still trying to shut itself off. So i forced the shutdown, restarted, but now i'm stuck with the loading spinner.
What can i do?
UPDATE: Verbose didn't show anything interesting. i also did the hardware test. Nothing comes up wrong. Disk utility did not find any error on the HD. But, it did show a fatal error when checking permissions.
