System Administrator
I got a dropdown on my Mac Mini from EPSON asking for a "System Administrator" and a PW for my Mac Mini, before it would allow software for my new printer, and the printer, to function. As the owner of this home computer it's not part of any system, just a fine computer (2014 Mini: OS 10.13.6) and an as yet to be operating printer. So, who is the administrator and how is that name or whatever entered (does it matter?), AND what is this password drawn from?
