Finding the right iCloud account
My contact list appears in my account and in my partners’ account on our iMac. Her contact list does not appear on the iMac or in her iCloud account. How can I resolve this so that she can see her own contact list? She does have an iCloud account. Anne King It sounds like all that’s happened is your partner is signed into your iCloud account on the iMac. To fix this, she should open System Preferences > iCloud, click Sign Out at the bottom-left and sign in with her own iCloud account. Her contacts should now appear correctly.
If your Mac has several user accounts, make sure each one is signed into its owner’s iCloud account if you want to see the correct contacts and calendars.
