Problems with installation UR44C on a brandnew Mac Studio

Have a new Mac Studio (the basic one) and got me a Steinberg UR44C audio interface with two KrK Rokit monitors. I can’t seem to get any sound out of my speakers. Read about problems with driver installs on MacStudio. But how can I see/check that the right driver is installed? (I’m a novice Mac user). I found a manual from Steinberg to override the limitations when installing drivers but all the paths to get anywhere differ from my possible choices…
Has anyone some tips where to look/get amanual to get this working? I would be eternally greatfull!!

Headphones outputs are working?

Headphones don’t work either. I tried both entries…

But the security settings are done?

What do you mean by that? :flushed:
