Accepted answer: no
This isn't a question about how to get the ps3 controller to work on the mac. Its assuming you've already done that. (support is build into Mountain Lion, some people just have issues getting it to work)
This isn't a question about what Mac (OSX) games support controllers in general. Many support the usb xbox 360 controllers. But few seem to work with the ps3 controller.
This isn't a question about how to get the ps3 controller to work with games that don't support it. (such as using gamepad companion or controllermate).
What I'm asking is do you know of any Mac games on the mac that actually work out of the box with a connect playstation 3 controller. (either via USB or Bluetooth).
I've only found one in my Steam catalog so far that works. I'll add it as an answer.
