I have a MacBook Air (10.13.2). I'd like to play videos full screen on an external monitor, while still being able to continue working on my MacBook.
I can't get it the way I'd like.
Whenever I click back on my MacBook, the dock and menu bar appears over the full screen video on the external monitor.
I've Googled and the only way I found to get rid of them is to uncheck the "Displays have separate Spaces" in System Preferences >> Mission Control.
However, that brings the unfortunate effect that when I switch to a different desktop than the one where I started the video, I lose the video on the external monitor as it too switches to a different desktop.
Anyone know how I can get rid of the menu bar/dock on the external monitor and still keep it as a separate space?
