MotionInJoy-like for OSX?

So basically, it's kind of great that a lot of games are getting OSX ports on Steam. Problem is, I like to play with a controller every once in a while, and games generally don't have great support for PS3 controllers. Is there anything like MotionInJoy for OSX where you can more or less emulate a 360 controller with a Dualshock 3?

Unless I'm mistaken, the DualShock 3 works natively with OS X through Bluetooth. I've never tried it myself, mind you.

EDIT: And apparently it doesn't work on 10.8.3 or Mavericks (and probably 10.8.4).
