The situation is not so rosy for macOS, the only officially supported platform for it along with Windows: the driver from 2014, last supported OS version is 10.10.1, installs, loads the kernel extension and its control panel detects the device is connected just fine on 10.13.6, but trying to play any sound from Ableton Live 11, Ardour 6.9 and Pro Tools 2020 results in the DAW’s locking up to various degrees with no sound coming out. I have the M-Audio Fast Track Ultra 8R audio interface which works great on Linux: all the internal routing is exposed in alsamixer including changing the effects on the internal DSP, the only thing I haven’t tried is MIDI and S/PDIF since I can’t find the breakout cable for it anymore.
I know this is not strictly on-topic on Ardour forums but this is the only place I could think of where free software, DAW’s, Linux and macOS are all relevant to a certain extent, so I hope you’ll forgive me.
