DJM 750 MK2

Hello,

I am being unable to use my new DJM 750 MK2 as an external soundcard.

The mac won't recognize it (Bir Sur 11.2.3), is not listed in the audio drop-off menus.

Rekordbox doesnt recognize it eighter. Although it shows in the Control Device Information section.
It shows as connected in the Sections Utility tool. 

I just purchased this mixer, if it is not compatible with Big Sur, when will the patch happen? 

I'm still within the 30 days of purchase, I am considering a refund. 

Thank you!
