Cannot connect a Focusrite to MacBook Pro

I will give a more thorough response soon, but the one thing I need to re-check with the teacher is whether the mic access has been allowed in settings. I wonder if this is the problem because I just had another session with a teacher that had the exact same problem. For some reason I had them re-install the JamKazam software, then at the very end it asked for permission to use the microphone. Without any other changes, the Scarlett device passed the initial test without any other changes. At the very least I will try to contact the client and make sure she has all those settings correct. My only concrn in her case is that I was able to get her going using the built-in mic and headphone jack, so that may not be it.
