Unable to add contacts to lists on iCloud on Mac
Sometimes I can't move a Contact to a List (group of Contacts) on my iMac. I've checked and the Contact isn't already in the List. Both the Contact and the List are in iCloud. Can anyone tell me what could prevent a Contact from being added to a List?
