The whole issue comes to the fact that the old Mac has a headphone jack but it also has another jack where I plug the Behringer X32 Board. It is shown in the following pictures.
The Old one is with the two jack where I can stream just fine but on the newer model I don't have the jack, which brings me to this issue. Which cable can I purchase to be able to capture the audio from the board on the new mac? Which cable should I buy to connect the X32? USB or Mic cable?
