OSX Build cannot go fullscreen?

Hi guys. So my build works fine if the screen is windowed, but if I go full screen, all I get is a black screen. Anybody know what's going on here? I found the same problem here ( http://answers.unity3d.com/questions/856397/desktop-standalone-not-working-in-fullscreen-mode.html ) but there doesn't appear to be a solution, or even a guess.... Thanks for all the help guys!
