Traktor Pro 3 with DJM 900 Nexus soundcard and CDJ 2000 Nexus HID setup [en-us]

I'm wanting to update from mac os 10.10.5 to 10.13 or later, in order to update to Traktor Pro 3.  I'm currently using Traktor pro 2 with DJM900 Nexus as Audio Soundcard device, and a pair of CDJ 2000 Nexus' in HID mode.  Are there any known compatibility issues with my current hardware setup that you guys know of?  I seem to remember something not being compatible the last time I wanted to update the OS a year or two ago, and that was the reason I didn't.  I don't recall what the issue was, but I believe it had something to do with using the DJM900 as a soundcard in Sierra or High Sierra...?  Anyone have any input, or currently using this setup with 10.13 or later?
