imac won't shutdown

[krunch]

My G4 imac(running 10.4.1) won't shutdown or restart except through the power button. If I select shutdown or restart from the finder, all the icons disappear but the desktop image remains and I can still move the cursor around. It just stays like that until I hit the power button...ok, here's everything I've tried so far, none have fixed it...
reset NVRAM
reset PRAM
run fsck through command line
run fsck through disk utility
repaired permissions
run cron scripts
logged out
nothing has worked, help me please....

How long did you wait. I had this happen a few times, had to wait about 5 minutes or so and it finally rebooted. Set your computer to reboot over night, and if its still the same way in the morning, you know you probably need to reinstall 10.4.

By the way, did you upgrade from 10.3, or do a clean install. How did you put 10.4 get on your old G4 iMac.

I think I waited at least 5 minutes but I will try your advice...I upgraded from 10.3.8...

Let you mac on for a couple of nights. In the night your mac does some cleaning. When you shut it down, it does that cleaning at that moment. You can also use programs to do the cleaning when you want, such as macjanitor or cocktail. Run one of these programs and try shutting down then, I think that would make a world of difference. BTW, has your mac ever been tied to a network? If so, when shutting down it could be signing off (or trying) to a network (if that even exists). That takes a bit of time. Give it a couple of minutes.
