Contacts groups duplicated hundreds of times
Question:Contacts groups duplicated hundreds of times
(China, Family, Miami) hundreds of times each. Each one of the hundreds of groups has all my business contacts. Same with Family and Work. This is only on my Mac. iCloud and iPhone Contacts app all look normal. I've already tried logging out and back into my iCloud account and the issue just reappears. I only have about 350 contacts total, but multiplied by the hundreds of duplicates, I'm guessing I now have hundreds of thousands of contacts duplicated, which is probably why Contacts is so unstable now on my Mac.
I know how to delete duplicates, but with hundreds and hundreds of duplicates, deleting one by one is not an option. Is there a way to delete multiple groups at once? Or is there a way to delete the Contacts app from OS X and reinstall just that one app? Or is there some Terminal command I can execute to delete all the duplicates?
