Default [Q] adb problem mac

I'm trying to jump on the S-off bandwagon. I can't seem to get my mac to see the device. I installed HTC sync-it saw it there, then removed program as suggested. I'm not sure if my problem is missing drivers or something in the way I'm trying to start/run adb. I'm trying to follow the instructions on the firewater site. I'm fine up until the point where I need to do the adb part.
