360 Controller on OSX | Not a TattieBoogle Q?

I am attempting to deploy on OSX, where the controllers have been thoroughly tested -in editor-. they work well in Unity, and in other games as well.

However the compiled and exported result does not recognize the controller. I thought perhaps it was simply recognizing the axis & buttons different, but trying to reassign them through the Input window (see image: http://i.imgur.com/SQ7K5kQ.png) does not detect the controller either.

Has anyone experienced this and resolved it? Or might I be missing something obvious? Any help would be appreciated.
