Game Crashes upon entering Load Screen (MAC)

For the last few nights around this time every time I try to enter a game it crashes when the loading screen pops. I can play with no issues during the day, I even played a full game earlier with no issue, it seems to only be occurring around this time at night. This has been happening to myself and my roommate. We both play on Mac platforms so this seems to be exclusive to that. This has been an extremely frustrating occurrence and it's unusual to me that it only seems to occur at night. Any response to this problem would be great because it doesn't seem to just be us experiencing this problem.
