The issue is when I launch Desktop Video Setup I get the message "No Desktop Video Device Detected." However, the device is connected to the Mac Mini using a verified working Thunderbolt 3 cable and the device's power light is on.

I'm running MacOS 11.1 Big Sur on an Intel Mac Mini 2018. I just received my UltraStudio Recorder 3G thunderbolt 3 device. I installed Desktop Video 11.7 before connecting the device.

Please help.

Desktop Video 12.0 was just released. Give that a try. Be mindful of the System Preferences Security & Privacy access that must be given.

Thank you. This is important information:

UPDATE: I figured out my problem.

For the Intel Mac-
Before Desktop Video can work properly it must be authorized by the user. Open System Preferences/Security & Privacy and on the General tab there should be a message about Desktop Video asking for permission to the system. Click the lock icon, enter your Admin password and authorize Desktop Video. That fixed the problem for me. Desktop Video recognized the UltraStudio Recorder and I had the option to use either SDI or HDMI input.

For the M1 MacBook Air-
A similar situation except there were message bubbles that warned that authorization was needed and gave instructions for shutting down and rebooting in a special way, holding the Touch ID power button until you enter a special boot mode to authorize Desktop Video. After authorizing and rebooting go back to System Preferences/Security & Privacy and make sure Desktop Video isn't asking for permission. Desktop Video should launch from the System Preferences then and you can configure the UltraStudio Recorder when it's connected.

All of this explicit authorization is something new for Mac users. Most every app that's installed and wants access to the system seems to need to be given explicit permission now in the Security & Privacy section of the System Preferences.

Apple is really clamping down on security. I had to go through this with my Recorder 3G with the 12.0 Beta on my M1 MBP. When I installed the 12.0 release version I didn't have to go through the special boot this time (only needed the first time) buy you still need to give in permission in Security & Privacy.

As I understand the release notes, the UltraStudio Mini is never going to work on the M1.

So I've run into this same problem and have tried all the recommended steps.

I have a new Mac mini M1 and assumed I'd be able to hook up my BM Ultra Studio 3D.

Plenty of UltraStudio products on the support list of BM's latest Desktop Video software release notes but not the 3D specifically?!?!
Does this mean I'm toast with the Ultrastudio 3D???

Think I'll need to buy a BM UltraStudio Monitor 3G??

her you will find the supported devices under big sur:

I'm not seeing my issue discussed here - so please forgive me if I overlooked it. I just changed over to a new Mac Studio (2022) running macOS Monterey. I have Version 12.5.1. The chip is the Apple M1 Max. I have 64GB of memory. I WAS using an iMac Pro 2017 and used the Blackmagic UltraStudio Express to enable a 3rd "clean feed" monitor while editing in Davinci Resolve. When running Blackmagic Desktop Video Setup ... this Mac Studio will NOT recognize the device (Ultrastudio Express). NOTE: YES, I have uninstalled and reinstalled. YES, I have assured I am using the newest download from BM. YES, I have performed the correct Privacy and Security resolutions. YES, the Ultrastudio Express IS working (the light is on). YES, I have checked all the cables - they work.

Please - ANY suggestions beyond that? Or, is there another set up I should explore?

Thank you

Actually, it turned out to be really simple. I needed NEW CABLES... all the Thunderbolt cables I had were no longer useable with the Mac Studio. Simple problem - same old crap from Apple... the second I plugged the Thunderbolt 3 cable - viola - it worked without a problem... why they do this crap is beyond me.

Were those really TB cables? USB-C ones look the same, but only those with a lightning symbol are TB.
