Occasionally, I find that I have duplicate entries in my Address Book. Well, they’re not really duplicates — they just have the same name. One may have work information, while the other might have personal details. Wouldn’t it be great if you could easily combine those two cards into one? Fortunately, there’s an easy way to do just that in Address Book.

How did I get two cards for the same person, anyway? Most likely, I imported a vCard attachment from an email, forgetting that I already had an existing entry for that person in my Address Book. Or maybe I just added another entry by accident, manually.

Regardless of how it got duplicated, here’s how to merge the two into one:

1. In Address Book, locate the two “duplicate” cards you’d like to merge. Select them both by clicking one one, then command-clicking the other. They both should be highlighted.
2. In the Card menu, select “Merge Selected cards”.



3. Voila! The two cards have been combined into one, with information from both cards!
