Do automatic installs of updates actually interrupt your session by surprise?
I'm in particular looking at "Install system data files and security updates"
Looks scary. Suppose I'm in the middle of something important. I walk away from the mac for a minute or two. Then I come back and find it running an update, which on my mac usually takes 35-45 minutes. Do I have that right?
And automatically install macOS updates? Same thing? No chance to prepare? For example, an update to Catalina would break all my 32-bit apps and make movies in old formats unusable, and then I wouldn't even be able to convert them to a newer supported format!
So would these automatic installs, if set, just run by surprise and possibly break things and interrupt a potentially very important session? Do I have that right? And if so, why would anyone want this behavior?
