Connecting USB433MHz groundstation to OS X 11APM Planner 2.0

I am running MacBook Pro with OSX 10.11, with APM Planner 2.0 installed. I plug in the USB 433MHz ground station. It says “Radio Telemetry 433MHz Ground” without any brand name, but I think it can be 3DR.

I have already installed the air unit on my quadcopter and connected it to “TELEM 1” port on the pixhawk, which has Arducopter 3.3 installed.

How can I make APM Planner 2.0 able to connect to my quadcopter?
