I have 2TB of iCloud storage, with Family Shared Storage turned on and several accounts in use by various family members. I would like to maintain a local copy of this 2TB, and I have a spare Mac to use for the job.
My issue is that, as far as I understand, macOS will only sync iCloud (files and Photo Library etc) for the currently logged-on user.
How do I set it up to automatically log into and sync files & photos from all of our iCloud accounts (e.g. every night)? I don’t want to have to manually rotate through changing users every time.
FYI I am comfortable with using Terminal, but not an expert Terminal user.
