Yes Mario, that's what to do, correct. I can't say for definite the 12.9 firmware actually bricks the US 4K Mini on Mac; It seems to do so mostly on Windows. But it does seem to stop working and be unrecognised at least on Mac too. I think you're probably on DR 19, which states a minimum DV version, of 12.9 is necessary and that could now be your problem.
I realise it's probably a bind now to go back to both DR 18.6.6 and DV 12.8.1; but I have a feeling that is currently the only solution for the US 4K Mini. Several people have said they flagged this to BMD support, who seemed unaware of it and have not yet acknowledged an issue. But I'm not going through a scary bricking again and so I'll wait to see if the next driver update sorts this. I'm back on DR 18.6.6 too btw.
