Mac User Can't Load Game At All

So I just got into a hexakill, and the loading screen didn't even pop up. My entire screen just turned black and stayed that way, and I couldn't do anything with my laptop anymore. No tabbing out or anything. It seemed to last indefinitely, and I had to press down the power key to force shut down my laptop. Game is still going on right now and I can't fucking reconnect, but my connection and everything are all fine.
