sidebar on left
How do I get rid of the annoying left sidebar on my big Mac...if I don't know if I'm using Safari or not?
iMac 21.5″, macOS 10.13
Sounds like you're in Full Screen mode.
Move your cursor to the top left hand corner of the screen, the window controls will drop down. The circled icon is the one you need:
Also the keyboard command
Shift-command-L
Will toggle the bar.
