MacPro refuses to Shutdown - Hang
Its been about a week, my Mac Pro 2008 doesnot shutdown.
Everytime I try to shutdown the screen goes to the background, arrow key moves, all folders disappear. I cannot click on anything and none of the keys work. It stays in this state until I have to hold down the power button to force shutdown.
I have tried to reset the PRAM and that didnot help.
I'm using 2008 Mac Pro with Snow Lepoard. About 2 months back I reinstalled OS and added a new harddrive.Everything worked fine until a week ago.
Some forums suggested going into System Preferences - General - and unchecking "Restore windows when quitting" - but I cant find any general section in system perferences.
Does anyone have any suggestions for this problem?
Mac Pro, Mac OS X (10.6.8)
