Behringer UM2 is not working on my macbook pro

Recently, I just got the Behringer UM2 audio interface in order to try out with the new condensed microphone. As the commercial of this interface said it should be able to be plugged and play right away, but I was having trouble figuring out why I could not connect this box to my laptop. All I got from my macbook was "The selected device has no input controls." I tried to find lots of ways to make it works on garageband so that I can do some recording but I still couldn't. Please let me know what should I do in order to make this work. Thanks a lot!

Some details about my Macbook Pro and the audio interface:

OSX version: 10.11.5 El Capitan

Processor: 2.9 GHz Intel Core i7

Audio interface: Behringer U-Phoria UM2
