I only require a way to monitor output on an SDI grading device, I don't need anything more than a simple Thunderbolt/USB-C to SDI solution. It'd be great for my sanity to know if BMD TB2 devices are simply not supported anymore but I see so many people having the same problems with the UltraStudio Monitor 3G that I'm loathe to run out and order one of those.

The only possible thing I can think of it being is the fact that this TB2 Mini Monitor is no longer supported but the manual only says that going from TB2 to TB3 is not supported - not the other way around.

I'd really like to see a video of the BMD engineers getting this to work.

No combination of OS and security preference changes or even selecting 'Allow' and 'Restart' in different orders has resulted in Blackmagic Desktop Video recognizing the UltraStudio device on my M1 MacBook Pro despite it showing up in the system profiler every single time. After that failed to work, I ran the uninstaller and tried the method above with disabling SIP and deleting extensions through terminal. I even used the Startup Security Utility before downloading the Desktop Video 12 beta installer.

This includes multiple install/uninstall procedures after each of the following:ġ) An initial installation on Big Sur 11.0.0 after a migration from a Time Machine backup.Ģ) A wipe and reinstall of the OS which was now 11.0.1ģ) An update of the OS to 11.1 (Beta, latest build)Ĥ) A wipe and reinstall of the OS back to 11.0.1 with nothing else installed first and no other device attached except the charger that came with it.

On my 13' M1 MBP I have tried every possible option to get Desktop Video to recognize my UltraStudio TB2 Mini Monitor device except the DFU mode - and that's only because I do not have another Mac with USB-C on it. Yeah, thought this terminal commands route was a long shot given how he was coming from a previous non-M1 Mac and Catalina. I am glad to be back up and running with my 3G under Big Sur! It worked for me, which made me think the leftover kernal extensions were the problem going from Catalina to Big Sur. If Desktop Video then says 'No Desktop Device Detected' you have to go to System Preferences>Security & Privacy>General and the select 'App Store and identified developers” and then “Allow” Blackmagic Design in the pop-up window. Open Terminal to enable SIP: At the prompt enter this command: csrutil enableĩ. After deleting the extensions, I rebooted in Recovery Mode (command-r)Ĩ. Sudo rm -rf /Library/StagedExtensions/Library/Extensions/BlackmagicUsbIO.kextħ. Sudo rm -rf /Library/StagedExtensions/Library/Extensions/BlackmagicIO.kext Sudo rm -rf /Library/StagedExtensions/Library/Extensions/Blackmagic_Multibridge_Driver.kext In my case, the commands looked like this for the three extensions: Once you reboot, open Terminal and force delete the kernal extensions. You will get a message that SIP has been disabled.Ħ. Open Terminal to disable SIP: At the prompt enter this command: csrutil disableĤ. Uninstall Video Desktop using the uninstall program.ģ.

Once I did all of this and then installed 12.0b1, it WORKED! Desktop Video recognizes the recorder and the picture displays correctly in OBS, using either SDI of HDMI.ġ. To do that, you have to boot into recovery mode, disable SIP, force delete the kernal extensions, then reenable SIP. So, I thought about getting rid of those. Then I noticed that the uninstall left 3 kernal extensions on my system: I completely uninstalled several times and reinstalled, but it was still the same. I tried installing 12.0b1 and got the same thing. The recorder was recognized, but all I saw was a black screen in OBS. I experienced the same issue as everyone else. I had Desktop Video 11.7 installed on Catalina and then upgraded to Big Sur. MY SOLUTION - UltraStudio Recorder 3G and Big Sur
