Open activity monitor minimized on startup

I sometimes like to have Activity Monitor running in the dock (to see CPU usage chart in the icon at a glance).

I didn't use it for some time though, but with a new mac I bought (El Capitan) I thought I'd activate it again.

Now I can have it start automatically but I always have to minimize the Activity Monitor window after login.

I think in the past6 I had set it with that option (to autostart at login via right-click on the dock icon) so that it started minimized but I can't seem to remember how.

Am I remembering wrong or missing an option?


Solution 1:

Does this not work?

First right-click on Activity Monitor and go Options > Open at Login.

Next, open System Preferences > Users & Groups > Login Items and tick Hide.
