I have two Dualshock 4 controllers plugged into my mac via USB cables to play coop with my brother, but the game seems to be bent on one of us using the keyboard and mouse because both controllers begin to screw up when they are both plugged in and both players cannot move properly as some of the controls are partially responsive or temporarily/periodically responsive or not responsive at all. How do I enable the game to recognise both controllers as seperate to each other and the keyboard so my brother and I can play normally? pls help :)

Also I forgot to mention that each controller works absolutely fine when the other is unplugged, the problems happen when both of them are plugged in :(
