I’m running 2020.3 on Mojave. Just installed it, so caveat there, but it seems to be working fine so far. It asks you to choose whether you are working with surround or stereo only. I choose surround even though I pretty much mix stereo. I think some of the setup options might be a little different now, but I got it to work, so I guess there’s no harm in choosing surround. I dunno.
Best,
