CDJs 2000nxs2 lag browse

I have lag when browsing tracks on my setup

DJM-900 nxs2 (LATEST FIRMWARE)

CDJ-2000 nxs2 (LATEST FIRMWARE)

CDJ-2000 nxs2 (LATEST FIRMWARE)

ALL are connected on new mac book pro with the the BIG SUR  using type C to USB AB 

I am using serato PRO dj and when I am scrolling to find a song from the 2000 it starts lagging 

I have brand new specific usb cables for the cdj's and I have everything updated to the latest firware and software 

any ideas?
