I recently installed the iTunes update plus 3 others that were in the list (don't remember what they were). After they installed, it said that a restart was necessary. I let it restart and when it came back the "beach ball" was spinning. The hockey game was about to start so I went off to watch the first period. When I returned the beach ball was still spinning. Thinking that there was no way it could take that long, I went ahead and shut down the iMac. I waited about 30 seconds and then turned it back on. It started normally and did not seem to have any problems. Is there something else I should have done? How long should it take the iMac to restart after a software update? The only other time the software updated was when I first got it. It had about 10 updates including the Leopard update. Every thing went fine that time. I have the 3.06, ATI, 4 gig, 1 TB iMac.
