Today, I decided to update both my MacBook Pro and my iMac. I usually do it both at the same time just for grins and giggles, but I realize after I came back maybe an hour that my iMac is sitting like this while my MacBook Pro has almost finished updating. After nearly 5 years of doing it this way this has never happened. What do I do? try to turn off the iMac and reboot. Or let it alone, what’s your take?
