Exit full screen ??????

Running Reaper on a mac (Yosemite) and can not for the life of me get out of full screen mode ! SMH !!!! I even uninstalled and re-installed but it went back to fullscreen . Any help is greatly appreciated . Thanks

Thanks i will try that tonight .

This also happened for me when I first started using a Mac. I made a window full-size with the expand arrow in the upper right hand corner. That was easy. Oh, wait - how do I get it to go back down? There was not a resize-smaller arrow that I could see. So, after learning 72 new curse words, and screaming them loudly at the Mac for a little over an hour, I had to swallow my pride, and call a Mac user friend. When I asked how to resize the expanded window he started laughing. lol Then he told me to place my cursor anywhere at the top of the page. It makes a drop-down menu with a make-smaller arrow. Or do like Eric explained: Fn+F11 Are we having fun yet? :-Don

FWIW, on my Mac (Catalina), I had to use Cmd+Fn+F11 F11 just shows the desktop for me!
