My iMac has been freezing up the last couple of weeks. It is locked up right now and I cannot access or change things with the mouse on the screen.
There is a pink circle segment in the center of the toolbar at the top of the screen??? Can anybody tell me what that means and whether there is a fix for what is going on with my iMac?
You apparently have had a hardware failure, most likely, and should take your Mac in to let an Apple Genius diagnose it.
