QGC and MAVProxy

I have a Mac laptop running QGC. I need to send and receive Mavlink info via the Mac. The only way I have found so far is to use MAVProxy to connect to the plane and use WIFI to connect between the Mac and the MAVProxy. Is anyone using such a setup? Alternatively, does anyone know of a way to directly connect a 5.8Ghz receiver to a Mac so I don’t need a proxy?
