Getting my PS3 Controller to work on my MacBook Pro

Any GWJ threads on setting up PS3 controllers to work with a MacBook Pro? I am trying to play Trine on my MBP with a PS3 controller.

I am having success "connecting" the controller, however I can't get the controller "paired". I don't know if "pairing" is necessary.

What is necessary is configuring the controller. I cannot seem to find a good way to do this.
