Rekordbox Interface 2 Problem

Hi. I bought interface 2. I have active account on rekordbox dj and rekordbox dvs. I have installed drivers. When i connect it to my mac it shows downscreen "Interface2 is connected" but at settings theres no option to choose it as an AUDIO system. It shows only "Built in". I'm sure i have installed good drivers and i'm sure interface2 is connected. My Mac is i5, 8gb ram, ssd.
