IMac will not shutdown, logoff or restart

I recently discovered a problem where my iMac will not shutdown, logoff or restart when I am logged in but will on the log in screen. I have repaired disk permissions as well as repaired the disk using disk utility but there has been no improvement. When I click the log out button, all the icons and dock disappear but then the computer freezes. I can still move the mouse around but nothing I do will log it off.


HI stangem,
Welcome to the forums.
Have you tried doing a SafeBoot? It performs maintenance on the computer.
if you perform a safeboot and your still having the issue. Have you tried another account? if so dose it have the same issue, or is the issue isolated to this one account?
good luck
