Big Sur and UltraStudio still not working

PostWed Jul 07, 2021 11:08 am

So according to this post by Tony Rivera, my Thunderbolt Ultrastudio Mini Monitor should work on my Intel based MacBook Pro running BigSur (11.4)
viewtopic.php?f=18&t=132745

Sadly this is not the case. I've install the latest version (12.1). When launching the "Desktop Video Setup" app it sees my UltraStudio Mini Monitor and says it needs a firmware update. This was run and successfully completed. Unplugged the Mini Monitor and plug it back it. "Desktop Video Setup" does not see the Mini Monitor nor do any of my video apps (Resolve, FCPX, OBS, etc).

My System Profile sees the Mini Monitor under Thunderbolt devices. So it's recognised by the system.

What's the problem? How do I get this to work?

I final got it to work.

I walked backwards around the block three times, then hugged my computer healing tree and now it works.


I installed and uninstalled 12.1 (following these steps in
) it didn't work tried again.

And today I reinstalled 12.1 from the same download as before and now it works.
No clue of what made it work.

yeah, been through all of that. no joy.

On one of my re-installs, before rebooting, I open the System Prefs and clicked on "Blackmagic Video Setup" which launched the app and my UltraStudio card was seen. Rebooted and it's no longer showing up.

Ugh!!!
