The UR22C is connected with a USB-C cable. And it’s working fine, the computer is detecting it and everything when I look in System Preferences → Sound. It’s just not being seen in the dspMixFx app.
What you describe sounds like the UR22C is connected via class compliant mode, which it is able to do without drivers… It’s the Yamaha USB Audio driver you need.
I’m not using my Mac theses days, so can’t check here.
I have the IDENTICAL problem. I’m on a MacBook Pro 2020 Intel chip, Big Sur 11.4. URC22C connected via hub, which has worked flawlessly for months. I’ve done NOTHING different. It is powered from the hub and the power is fully on and I can set my audio to go through it successfully.
I’ve gone through the Steinberg website and uninstalled/reinstalled all software and I still get NO DEVICE FOUND in dspMixFX. In the Audio Midi setup the symbol for the Steinberg is a BLUE USB symbol, neither the black found in the troubleshoot or the red it is supposed to be. I’ll paste a screenshot at the bottom. I’ve gone into security/privacy after reinstalling and there’s no option to allow privileges for this software. I did see in the e-license control center where it wants an activation code-when I first installed the product I entered the code, but now it wants it again and I don’t have it; however the problem began BEFORE I did the reinstall.
The ONLY thing that changed on my computer was that I just installed Google Drive desktop and I had to give permission via Security & Privacy for that product. I can’t tell you that dspMixFx was detecting the UR22C immediately before and now it has stopped, but I do know that as of yesterday it was detecting it. I got the “no device found” after the reboot from installing Google Drive Desktop.
Help!
Pasting screenshot of audio midi interface below, hope it works:
Update-after going through that whole software removal, reinstall and multiple reboots still no success. Out of desperation I updated my Mac OS to Big Sur 11.5.2 and this time, when checking the audio midi interface I saw that the USB symbol had become red, as it should have been - but the dspMixFx STILL wasn’t detecting my UR22C. One last reboot and now it has found it. So on to the next problem - the various effects aren’t loading! Anyway, as far as the UR22C not being detected, I think I’m OK.
Maybe that is good for M1 but for macos Monterey doesn’t work in my opinion Steinberg must to advice all buyers that its not working with macos monterey 12.2
I have the same problem. Was able to get to your #1 step but there was no “allow Yamaha Corporation”. There was only 2 choices on the bottom that you can click which are.
