Mac (Yosemite) Client crashes and bug splats

First of all, here are my specs:

Mid 2012 13-in MacBook Air OS X Yosemite 10.10.1 Intel HD Graphics 4000 1024 MB

I updated my computer from the previous OS X to Yosemite yesterday. Before I updated my client it worked perfectly fine, but after trying to play today I have been crashing multiple times per game and it's completely unplayable. I get a bug splat multiple times per game until I give up. Even the patcher will not load after trying to reload the game from a bug splat. It takes multiple times to open the client and once I am successful and load the game, it will bug splat either immediately after reconnecting or shortly after.

Any help would be appreciated.

Thanks.
