IMac problem
This morning when I turned on my iMac which is about 15 months old and running latest OS, the menu bar is not there. I can get apps to open but they are non functional. For example mail will load but I can’t open any of the emails. The area to the left that list inbox is grayed out. Web page will open but I can’t select anything on them. When I go to the top of my screen and right click there is no option to exit full screen. What could be wrong. I have tried shutting down, in plugging, restarting. Any help will be much appreciated!
iMac 21.5″, macOS 12.2
