OSX mfi support?

Hi, Does the latest osx release (1.3.0) support mfi controllers? i have el capitan and i cant get my steelseries nimbus controller to work. When the app launches it says “nimbus not configured” at the bottom of the screen. Also, i tried via bluetooth and usb. I go to input settings and try to bind all but get no response.

Ive established that both the left and right analogue sticks are both being recognised, but none of the buttons or triggers. This is a good thing right? i just need to find out how to make the other buttons work. Any ideas? Thanks.
