Duplicate Contacts
I have 2 of every contact on my iMac. Everything is synced with iCloud. If I log into iCloud, there are no duplicates. I also do not have duplicates on my iPhone, my iPad, or my MacBook Pro. It is only on the iMac. I have tried the recommended fix. I turned off syncing in Preferences. I deleted all the contacts on my iMac. I turned on syncing again in Preferences, then opened up contacts on my iMac. All the duplicates are still there.
This is extremely irritating! Please, can somebody tell me how to fix this?!?
