Steinberg Download Assistant does not start

I’v bought UR2mkII with free download of Cubase Elements.
The download assistant doesn’t work in MacOs Ventura.
Can anyone help?

Hi and welcome to the forum,

Does Steinberg Download Assistant show any message, please?

Hi Martin.

No message is shown. The app seems to star for a split second and it disappears.

I’ve never worked with Mac. But I would think that it must have system logs, like the Windows Logs in Windows ? It might be very helpful to diagnose your problem.
