Tried older versions of desktop video, switched cables.
The Ultrastudio is detected after first reboot.
But when I start the MacBook again itˋs not working anymore.
Tried different solutions i found in the forum, nothing worked.
Maybe it’s MacOS 11.4.
1. unplug the ultrastudio
2. uninstall desktop video
3. open the security&privacy control panel
4. unlock and let the general tab open
5. install desktop video 12.1
6. allow in the general tab (if asked)
7. push restart in the installer
8. plug in the ultrastudio
if this does not work, use an other TB (with a flash and a 3 printed on the plugs!) cable (shorter are better)
