Does anyone know if there are any controllers out there that actually work with STEAM games? Namely, Call of Duty Modern Warfare 2? I've used my PS4 controller with the USB cable and the controller works in the STEAM "BIG PICTURE" mode but once the game launches, the PS4 controller doesn't work anymore. Does the Steam Controller work? I'd happily purchase if I know for sure it'll work in the actual game. There's also this: https://9to5mac.com/2016/08/23/connect-dual-shock-4-controller-wirelessly-to-mac/ Just announced today. Any idea if this might work? Thanks in advance. EDIT: Forgot to mention I'm on iMac and MacBook Pro, all relatively recent versions. Only a few years old.
