When I open up Minecraft, it automatically goes 'full screen' and covers my entire desktop. It can be played as usual, but I prefer having it split screen with YouTube while I am playing, and since Minecraft is fullscreen, I can't do that. I tried to perform the three finger swipe gesture, but Minecraft simply minimizes itself.
Is there a way for me to make Minecraft not fullscreen? I have a MacBook Air 13".
