DDJ RZ + Built-In Output problem

Hi
I have a problem with the master output and the macbook loudspeaker. (pictured) 1.10 firmware, Rekordbox 5.0.2, mcOS Sierra. I reinstalled a Yosemite system, DDJ RZ 1.06 firmware, Rekordbox 4.5. The problem persists. Macbook pro 15 "2014 mid. I do not want to talk to your laptop speaker! What's the problem? Thank you everyone
