How to stop screensaver with a keyboard button press, rather than a mouse button press When then screensaver is activated, pressing a button on the keyboard does not stop the show and display the lockscreen.  The system bell chimes, but the screensaver show continues.  If I press a button on the mouse, the screensavers stops and the lockscreen shows.

It's been a while, but I remember being able to stop the screensaver by pressing any key on the keyboard.  Is there some way to re-enable this functionality?

Edit: I'm running 10.13.6 (17G65) High Sierra.
I fixed it by following the instructions from this post, which, oddly enough, didn't come up when I searched for it before making my post.

Anyhow: I did the following:


  System Preferences > Mission Control > Displays have separate spaces: checked


Which now allows me to stop the screensaver by pressing a key.
