I can’t get anything to go full screen
When using Safari on pages like Youtube, I can’t get any videos to go full screen, and my Launchpad app won’t open whatsoever.
I’ve cleared all of my history on Safari, and can’t find anything in my system preferences that looks odd or would be contributing to this. Any suggestions?
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
