Using ps4 Controller on Mac

[Bryze]

My first experience of Kerbal Space Program was on PS4. I put a lot of hours into it. As I discovered later it's behind the current release and it's tendency to corrupt save files is now legendary. So, I figured, let me try it on my Mac book pro. Mouse usage has been great. Flight controls leave a lot to be desired. When I connected up my ps4 controller, I couldn't help but notice that the controls are behaving like the keyboard. Yaw and pitch are just on and off, despite having full analog control on the ps4 version of the game.
 

My basic question is, does anyone know what the best ps4 controller setup is for Mac? I'd like to be able to do more that just throttle on/off and binary movements. It's so bad that I'm just sticking to the keyboard until I can find a solution to this. Before you say "use big picture mode", I've tried that and KSP hangs or crashes on startup if I enable big picture mode before starting.
