Fix corrupted Contacts database

Same thing happen to me. Duplicate of every contact (4,000+) and every group (70+). Apple support had me merge the duplicate contacts, but I had to delete the duplicate groups one by one. Annoying. Now I want to upgrade my work computer to Monterey, and am concerned it will happen again.

I hate upgrading!

yes, you did the right thing- in Contacts, select all, card> look for duplicates> merge. it takes about 30 seconds and your problem should get solved. you might have taken longer time since quadruplicate.

It may be possible to create an Automator script to help clean up your Contacts file by exporting vCards for each individual. Duplicate vCards could be discarded and the Contacts file rebuilt.

I don't have much to add but I did see duplicate entries at one point. I changed Contacts to use iCloud (which also syncs an iPad) and redid the (small) contact lists for the 2 accounts on the Mac.

The contact lists are stable but I did notice that there can be additional information added by Siri (e.g. a phone number gleaned from Apple Mail).

That is too bad.

These ASC forums have a lot to offer and persons with ions of experience, skills, knowledge and experience to offer.

All the above by fellow Apple User helping other Apple Users and on a volunteer basis - not costs involved.

Get assistance without a Big Credit Limit is a luxury these days.

Same thing here. Duplicate merge works, despite being scary as heck. And deleting duplicate groups is painful. The scariest part is that it's happening because something is wrong with the way Apple is handling my data. Where else is it duplicating it to? What happens when it just decides to delete it instead of duplicating it?

Good to know.

how do I clean up all the repeated contacts now that I have updated to Monterey 12.1. I now have several of the same contact copied
