Method 1. Merge Mac Contacts duplicates with the built-in feature

Mac Contacts app itself offers a feature for users to handle duplicate contacts. With this built-in method, three facts are worth noting. It provides only one option to deal with duplicates: Merge. It will find and merge duplicates in one go. It won’t let you know which contacts have duplicate cards. Therefore, you have little control over the process.

If you want to have more control and options, you can check out the second method.

Below is how this one works.

1. On your MacBook Pro, MacBook Air, or iMac, etc., open the Contacts app.
2. From the top menu bar, select Card > Look for Duplicates.
3. A window will pop up, informing you of how many duplicates will be merged. Click Merge.
4. Repeat the previous two steps until no duplicates are identified.
