ur setup on Mac

I’m trying to setup my UR audio interface on a new Macbook, but it doesn’t recognize the device. When I choose (ASIO)audio setup it shows built in sound, airplay, and HDMI. I do have an external monitor connected to the MAC using HDMI cable. I don’t know if that has anything to do with the problem. I’ve checked all connections and restarted. In the Mac system preferences I checked the sound settings and there’s no device. Any help is much appreciated.
