Sorry for the slow reply!
Your Dualshock 4 ~should~ work, but if your pad identifies as something different to mine, it will default to xbox mapping. And if your driver maps differently, it will have incorrect mapping by default.
If you check the GamepadTesting scene (in the Utilities folder) and see what name the gamepad is listed as, you can check the PS4_osx common mapping and see if the name is listed. If not, add it to the list of gamepad names and assuming the mapping is the same, it will work.
If the name is different or you need to make different mapping for it, please let me know (and maybe send me your common mapping asset) and I can include it in future versions :)
hope this helps!
