Adding to contact List.
Some contact cards cannot be dragged to a List; some can. What is the problem?
MacBook Air, macOS 26.0
Hi,
To add contacts to a list on a Mac, open the Contacts app, create a new list by clicking the Add button and selecting New list, and then drag one or more contacts from the main list into the new list in the sidebar. Alternatively, you can select the contacts you want to add and go to File > New List From Selection to create a new list with them already included.
