I finally got it!! Here's what I did if anyone else has problems on a mac:

Was able to get it to work using Ubuntu through VMWare Fusion
1) Make sure phone is connected to Linux by going to "Virtual Machine" --> "USB" --> "Connect High Android 1.0"
2) Ran revolutionary through terminal using "sudo ./revolutionary"
3) Copy and pasted serial/beta key as described on this thread many times
4) Program froze on "zerging root..."
5) Letting terminal sit there for a few minutes, I checked the "Virtual Machine"-->"USB" and noticed the phone had disconnected. Clicked on "Connect High Android 1.0" again
6) It completed root and rebooted to fastboot twice and gave me s-off.
