Topic: Big Sur & UFX II: firmware update and drivers after reboot

This is my setup:

Fireface UFX II
MacBook Pro (Retina, 13-inch, Early 2015)
3,1 GHz Dual-Core Intel Core i7


Problem 1: Can not update firmware

I can not update the firmware. Clicking on the "Update" button in the Flash Tool does nothing.

RME USB Series Flash Tool shows "Revision 15"
On the unit itself it says SW Version 11 03/2018


Problem 2: Driver not working after reboot

Things I have tried:
- trigger-panic-medic: https://forum.rme-audio.de/viewtopic.php?id=33277
- kext explicit consent: https://forum.rme-audio.de/viewtopic.php?id=30462
- installers versions 3.25 and 3.26
- another USB cable and another USB port

In all cases, communication with the UFX II works immediately after running the installer, but not after a reboot.

Re: Big Sur & UFX II: firmware update and drivers after reboot

After several more attempts, and going very slowly, it worked.

I installed 3.25 and used this trick: https://forum.rme-audio.de/viewtopic.php?id=33277

After running the installer and authorizing the extensions in Security & Privacy, I then waited for at least a minute or two before rebooting.

The firmware update also works now.
