Adding Apple IDs to Macbook

A single user should never have more than one Apple ID.

If you're preparing the MacBook for multiple users, set up separate User Accounts for each one, then set up an Apple ID for each one. If these are family members, you can set up Family Sharing do they all have access to shared apps, music, photos, etc.

To set up additional user accounts, go to System Preferences > Users & Groups > click on the " + " sign under the left sidebar.

You should stick with just one ID. If you absolutely must have a second ID you will have to add a User in System Preferences to create a new ID.

Once you have setup an Apple ID in another user, you can add it to System Preferences > Internet Accounts in our Main User Account. The second Apple ID will have limited options. You will only be able to use Mail, Contacts, Calendars, Reminders & Notes to sync.

In App Store you would have to use the sign out for account to switch to the other ID.
