Trying to restart, but can't quit Safari.
I am trying to restart, but am told to quit Safari, which is greyed out. So not an option.
Keep reading to engage "option" button, among others, but I don't have an option key.
My keyboard is designed to work with either Mac or PC/ I am on an iMac. Need to restart,
because I keep getting beachballs on my screen.
How to do this?
iMac 21.5″, 10.15
