Though it's not designed for use with Mac, it's easy to. Keen Mac gamers should consider hooking up Sony's DualShock 4 or Microsoft's Xbox One controller to a Mac to improve their gaming setup. With OpenEmu, it is extremely easy to add, browse, organize and with a compatible gamepad, play those favorite games (ROMs) you already own.
For the first time, the 'It just works' philosophy now extends to open source video game emulation on the Mac. OpenEmu is about to change the world of video game emulation. I open FF7, and although it registers the fast forward button (r2), nothing else works in game (start, X, directions).
Bought a 3rd party ps3 controller on amazon, ran fi.sh to get it to register the Bluetooth in openemu, and it works! I can map the controller no problem.
