Confusion about System Preferences


  • Subject: Confusion about System Preferences

I am confused about the way system preferences are organized (or preferences in
general).

I read the man page of defaults(1), but it is still unclear to me what happens
when I do, for instance,

  defaults -currentHost read com.apple.screensaver idleTime

as opposed to

  defaults read com.apple.screensaver idleTime

I get different results in the two cases.
Yet, the System Preferences GUI shows me only the value I get from
"currentHost",
and that is also the idle time after which the screensaver on my laptop gets
launched by macOS,
so it seems to be he only value I should care about.

So, what is the significance of the value of the version without "currentHost" ?
When is it important?

Thanks a lot for all insights.

Best regards, Gabriel
