Topic: [Solved] Fireface UC causes my mac to restart

Hi,

A few days ago when I plugged in my fireface UC it restarted my mac and caused a kernel panic. I'm running Big Sur 11.7.10 and the erorr report that I recieved is below. I'm not aware of any recent changes to anything and I have tried re-installing the Mac OS. The fireface seems to work ok on my windows pc. Any help would be very much appreciated!

Re: [Solved] Fireface UC causes my mac to restart

When you plugged in the UC, did you change it to AP mode first?

Re: [Solved] Fireface UC causes my mac to restart

Thank you so much! I don't know how the mode got changed but it had been so long since i changed it that I had forgotten all about ap mode!
