OS X Big Sur UR22C audio driver doesn't work

[andrelee]

I just figured it out!

Steinberg UR44C DspMixFx - No Device Found

Turns out the driver installation was never completed. I found this on the support page (can’t post a link): macOS: Audio interface not working properly / cannot be selected in DAW / missing in Audio MIDI Setup Here’s what I did: Install Yamaha Steinberg USB Driver V3.0.5 Direct to system menu/ preference/ security and privacy/general tab Allow Yamaha Corporation Install Yamaha Steinberg USB Driver V3.0.5 again I hope this helps.
