Unfortunately I'm not very familiar with how to fix this on mac, I'm a complete mac noob. I'm sure Nate or another more mac savvy person can help you out. With that said, this is something that will be fixed as soon as the new launcher is released, just a few more fixes and then we will have it out, hopefully within the next couple of days.
This will possibly help. http://support.apple.com/kb/PH14369
