DJM900NX2

I am unable to find the DJM900NX2 appear im rekordbox as and audio output device in preformance mode. I have installed the driver via rekordbox. All features of rekordbox export via lan connextion beteren moxer and CDJ2000NX2 is all working as described. The issue is in performance mood, where the only output option here is built in audio, which is my Mac speakers. Also seems that the assignmnet of CDJ deck numbers are scewed with the mixer. I have tried all 4 chanels on all output options also but only one chanel is plaging out audio to the laptop. The djm utility says that all is connected.
