Is there any program I can use to hook up my PS3 Controller to iMac?

i cant remember the name of the software but a while back I did this on windows via bootcamp and it worked great. so there is something out there you just have to find it

In Lion+ there are drivers built in to OS X. You just have to pair your controller. Unfortunately, it's a bitch doing so, because of an apparent bug.

Here are the instructions though:
