I find the LogiTune software good enough for managing my Brio webcam. Certainly less buggy and frustrating on Mac than some other official software I tried previously.
Unfortunately, the C920s resets all its setting when losing power.
I'm using it on my home computer and my work laptop, but don't want to install the software on the work laptop. So I must live with the extremely wide FOV there.
I have a script which runs after login and after resume from sleep. It runs guvcview (Linux tool for managing webcams) and loads a saved profile that has my preferred zoom and focus settings.
