Adding a User to an Existing Home
I have a Home set up already. My wife got her first Apple phone, but I can't find a way to add her to the existing home. How do I go about doing so?

Each user has their own home directory. They are not shared. Use separate Apple IDs. Ideally, one administrative account. A Time Machine backup to an external drive 2.5 - 3x your internal drive capacity will backup all user accounts and respective files on your Mac with each hourly run.
