I was stuck in Fullscreen Interface mode for a while as well on my MAC and finally realized that if I move the mouse all the way to the top of the screen, the menu bar will drop down and then I can select VIEW and select FULLSCREEN INTERFACE again and it will take me out of fullscreen mode.
Although on the Mac in the menu it says that F11 is supposed to be for Fullscreen Interface mode in OBS, it does not work... clicking on F11 usually adjusts volume on Mac and holding down function FN+F11 on the Mac does not enter Fullscreen Interface or exit Fullscreen interface mode.
Turn off the default "Show Desktop" shortcut for F11 in System Preferences > MIssion Control
or anything else that might be set to F11 in there and is overriding the OBS shortcut.
