Unable to add contacts to lists on iCloud on Mac

Thank you so much Francesco Rocca! That worked! I've been dealing with this problem for years :0

Best wishes,

No, it is not helpful at all: The described problem is a bug, unaddressed for years.

Not helpful to repeat your explanation how it _should_ work.

Hello croshaven,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with adding a contact to a list on your Mac. Try the steps here to see if they resolve the issue: Create and change lists in Contacts on Mac - Apple Support

"Add contacts to a list

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."

We hope this helps.

Cheers!

I have discovered if I do two or more operations like adding a card or two, I am unable to add them to a list or edit a list. But if I shut the application down and wait a few minutes and reopen the application, I can then edit lists or add to them. It seems the application can tolerate one or two operations on lists until it cannot anymore. Than I have to shut it down again and restart it after a few minutes. Is this an issue with iCloud? It is annoying.

Thanks. I had the same problem with not being able to drag contacts to a list. Disabling and re-enabling iCloud worked. Apple, please fix all these Ventura glitches.
