I'm trying to use a Steam controller on Mac OS X. Steam recognizes the controller, but after starting JNPG in Big Picture Mode, the controller vibrates but does not seem to be recognized by JNPG. When attempting to change from Mouse to Game Pad, the Game Pad selection screen shows "unknown controller" and runs a 30 second countdown during which I have no keyboard, mouse or controller input to make a selection.
I have tried connecting the controller by every method, bluetooth, dongle and cable with no effect. The controller is recognized and usable in other games.
Any thoughts?
