Hello everyone, I'm having a huge problem and daily fits with my overly active cat and Mac Book Pro. The problem is he is always on my mac and just press the keyboard buttons (one time he decided to invert the colors of the screen for example). Is there a way to lock the internal keyboard (preferably with a shortcut)? I don't one something that would lock my screen, because I want to watch movies and stuff on it without my cat changing the aspect ratio or such. Is it possible or is it just a dream. Thanks!
