Ultra studio Mini Monitor

Dear BM forum,
I have a Mac Pro Trash Ca 6.1 running Ventura (with Open Core Legacy Patcher) and running the penultimate version at Avid Media Composer.
It all runs great but I cannot get my recently purchased Blackmagic Ultrastudio mini monitor to work.
I can see it in machine system report but it does not show up on the blackmagic software.
Can anyone please help?
Thank you in advance.
Best
S

If that is the older Mini Monitor (TB 2), use an old version of the drivers too, I'd suggest 12.9.
