If you see duplicate contacts after setting up iCloud Contacts - Apple Support
I've run the instructions - particularly for the Mac - steps On your Mac
On your Mac
2. Open Contacts.
3. From the Card menu, select Card > Look for Duplicates.
4. When asked, click Merge.
5. Repeat steps 2 and 3 until no duplicates are found.
I've repeated those steps more than a dozen times and every time I get a seeming random number of cards.
After running the steps, I literally watch as duplicate cards come right back and repopulate in contacts on my Mac.
Also, what's the point of steps 1 and 6. So, you've made copies? What's the point?
I have confirmed the duplicates are NOT in iCloud. And, Contacts is ONLY linked to my Apple iCould account - not other card accounts (e.g. Google).
There is no need to tell me to make sure I have updated software, latest version of MacOS X, etc. and similar cut and paste - here's a whole lot of worthless things. Those instructions are insulting and nothing more than a user/forum "points" grab.
Also, Apple's own instructions above are poorly written (in addition to not working). The implication of "repeat" step 2 is to Open contacts. So, shouldn't there be a step 4.5 to quit/close contacts before returning to step 2 to Open contacts and run step 3? And, by implication, are you supposed to NOT repeat step 4 each time you're told in step 5 to "repeat steps 2 and 3."
