Episode 1523 (11:55)

Dale from Santa Monica, CA
Contacts on Mac

Dale has an Apple and Outlook contact list. He'd like to merge them. How can he? Rich says that the iPhone doesn't do a good job where the contacts are located. But the Mac contact app does. So Rich says to sync all the contacts to his Mac. Add them in his contacts app, and then sync it. Then, Rich recommends using Google contacts as his main contact manager. He can add his Google account in there by clicking the plus sign.
