Mac FPS Controller keys not responding

Hello, On my Mac, when I place a FPS controller into my scene, press play, press the keys W, A, S, D to move my FPS controller, it does not move. On my PC, these keys move the FPS controller.

Are there keys on the mac I have to set? Just wondering why they keys on the mac aren't moving the FPS controller.

Thank you.

You have to reassign FPS keys under the Preferences->Keys menu.
