It was complied and tested on 10.11, does it crash the whole MAC or just the application? Thanks for playing.
It crashed the whole Mac for some reason. At least my whole screen went black and none of my keyboard keys functioned. So I had to use the power button. I know from my own programming experience that the code for OS X 10.7+ is different than 10.6 when creating fullscreen apps. Not many using 10.6, so I wouldn't worry much.
