Lists (Groups) in Contacts app on MacOS Ventura not accepting new contacts

Hey ShaneMcD,

Thanks for that additional information. One other thing we'd like for you to try is starting in safe mode and see if this allows you to use the method that you mentioned. Safe mode can help tell us if the issue is possible login items. Be aware that internet access is limited in safe mode, but sometimes just starting in this mode and then restarting normally can resolve some issues: How to use safe mode on your Mac.

Keep us updated.

Hello ShaneMcD,

We have a great support article that might help with this. It outlines all the ways you can work with your Contacts list on your Mac. Please take a look at it here: Create and change lists in Contacts on Mac - Apple Support. Follow this guidance:

1. "In the Contacts app  on your Mac, select one or more contacts listed in the sidebar.
2. There’s no limit to the number of contacts you can add to a list. If you use more than one account in Contacts, make sure the contacts you select are in the same account.
3. Drag the selected contacts to a list in the sidebar.
4. If the contacts aren’t added to the list, check if it’s a Smart List—you can’t add contacts to a Smart List.

If you use an Exchange account in Contacts, those contacts can belong to only one folder at a time. Any contacts that aren’t in a folder you create are in the default Exchange Contacts folder."

If this is not working as expected (as explained above), a simple restart might help resolve the behavior as well. Follow this page: Shut down or restart your Mac - Apple Support.

We hope this helps. Let us know if we can assist with anything else at all. Take care.
