Just downloaded app and now screen is blank. How do I close the app with the key board?
I just downloaded a app. I opened it and the screen went blank. I don't know how to close the app so I can access my mac. I have tried shutting it down and re-starting it. That didn't work. So how do I shut the app down with the keyboard?
MacBook Pro with Retina display, iOS 7.1.2
