I would run a spyware and av scan on your computer just to be on the safe side. I know that you have a mac but when you install beta software screwy things can happen. If that doesn't work i would try to revert back to a restore point if you can.
I am sorry that I don't know that much about macs but I am sure that others do.
Cheers
