Two months ago I bought a RME BabyFace Pro FS and are using it together with my Nord keyboard/ MacBook Pro (OS Big Sur 11.4)/Logic setup. Until a couple of days ago this has worked fine, but after a restart on my Mac the software suddenly didn’t appear as usual. I tried to locate the BF in Preferences/Sound, but it wasn’t there either.

I have tried to reinstall the driver several times, and the same thing happens every time:
1) Downloading driver (driver_usb_mac_325)
2) Installing the driver successfully — and at that time the TotalMix window pops up and everything is working
3) But then, when I restart my Mac (according to the dialogue box and the only way out of the installation process) the BF disappears again. Can’t find it anywhere, the TotalMix window will not open and the Preferences/Sound doesn’t show the BF alternative.

Happy for any suggestions.
