Hey there,
I've been having a problem with a Blackmagic 4k (the TB2 Rackmount version) where it seems unable to be detected by Desktop Video under any circumstances. I tested a variety of aspects, including daisy chaining through to a monitor to see if it was receiving data, which worked, the device shows up in the system report, and on all iterations my older Mini Monitor shows up fine in Desktop Video.
I've currently tried it on 2 different computers, both running MacOs 10.15.3, then on a third system running a fresh install of 10.14. I've tried uninstalling the drivers and reinstalling Desktop Video. I tried that with 11.5, 11.4.1, 10.7, and 9.5, just to see if an older version would work but all of them had the same results (miniMonitor works, 4k doesn't). I know there's 'security' preferences, but not only have I pressed allow on everything in the security preferences, I don't know how that would interact with one device and not the other
I've contacted the original owner who swears up and down it worked on his system (and I believe him)
I'm reaching a point of not really knowing what other elements I can change to see what's up with the device and checking to see if there's any advice out there
