Is your Mac’s Address Book teaming with duplicate contacts? Do you have multiple cards for the same people—one with the home number, one with the work number, and one with the mobile number?
Have no fear! OS X has a built in shortcut to help you tame your Address Book contacts in no time.
If you can’t remember the shortcut, go to the Card menu and select Merge Selected Cards (or you can search for it using the Help Menu).
The only downside of this approach is that you’ll have to go through your contacts, one-by-one. However, the granular level of control you have over your contacts more than outweighs this.
