Topic: Fireface UFX+ thunderbolt Mac OS 11.6 not loading on startup

I have an Intel iMac 2019 running Big Sur 11.6. Just in the last few days the computer will not recognise my Fireface UFX+ on startup, and TotalMix FX will not load. I have the latest driver version.

At the moment to get the device to work I either have to reinstall the driver and not reboot, or enter in the command "sudo kextutil -v 2 /Library/Extensions/RMEPCIeAudio.kext" in the terminal every time I start my computer.

Is there any fix for this so I don't have to do these steps every time I want to use my interface?

Many thanks,

Thomas.

Thanks for that - it works now!

Do you foresee any problems if I upgraded my iMac to macOS Monterey? Are the drivers compatible?

I did upgrade from BigSur to Monterey and had no issues.
All interfaces are working fine as expected.
