M4 and Loopback

Post by lydian91 »

I just received my M4 today and I'm having trouble with the optional driver. The loopback inputs are not appearing when I launch DP. The driver is definitely installed (Mac HD > Library > Extensions > MOTUCoreUAC.kext). I have tried resetting PRAM...no luck. The interface is otherwise working properly. What am I missing?

What OS are you running? I'm pretty sure it needs High Sierra (10.13) or higher.

Have you tinkered with Audio MIDI Setup? Is there some other config panel app that gets installed with the driver?

I'm on 10.15.7 (the latest Catalina I believe). I have explored Audio MIDI setup with no success. I am not aware of any companion app or configuration panel. It seems like MOTU wanted to go the minimalist route.

Have you added the driver in the Security Settings?

If not, reinstall and add them per the instructions below. You have less than a 30 minutes after installation to do this.
