Connection issues with Spektrum DXe on Mac

  • I just got RC8 and I'm trying to connect my Spektrum DXe to my 2019 Macbook Pro. I have an AUX to USB3 cable that I'm using. When I go to scan for a new controller in RC8 it isn't recognized. I've tried having the controller powered on and off and plugging in the AUX. I've looked for a mac program that will recognize inputs from my TX but I haven't found anything. I ordered an AUX to USB2 cable so I can plug into my other computer but this is making me wonder if that is going to work.

    What is my next step here?
