I'm left with a black screen and a large cursor arrow. My mouse won't work. My computer feels really hot. My only recourse is to unplug the computer, wait a minute, replug, then push the start button on the back. This works but doesn't allow any iMac updates. Why can't I restart from the menu, or shut down from the menu?
If the above fails, boot in Safe Mode and see if you iMac works as expected. If yes, reboot in normal mode.

iMac won't shut down completely or restart
