So macOS security updates have been coming fast and furious recently and I was wondering the best way to deploy them? Before the start of school I tried setting this up but it wasn't working as intended and I ran out of time. At the time I was updating to Catalina 2021-004, but instead on the one computer I scoped it out to, it was getting 2021-003 which is not what I wanted since it breaks AD logins. I see now 2021-006 (19H1419) is out and thought I might give this another shot.
Is there a site or a video that shows how to properly set this up? I tried this one from YouTube but I can't quite tell if I can use it for security updates https://www.youtube.com/watch?v=MBc4ns0D7SM&t=179s.
