Mac Full Screen Black screen

Whenever I press fn + f11 to run full screen on the latest version of minecraft, it turns my screen black. Even when I put on full screen mode it turns it black. I can still hear noises and press menu buttons and things like that, but I can't see anything. How do I fix this? This is not resolved yet despite what the status said, some mod said it was a duplicate of another glitch and it is not.
