Part-time cottage dweller and full-time Mac 911 reader, Laurent, would like to merge Address Book data between two Macs. It is written:
I use a G5 at home and an iBook at the cottage or on the road, both running on 10.4.7. I’d like to be able to synchronize my address books since I enter data in one or the other depending on where I am. By synchronizing, I do NOT mean replacing the AddressBook.data on one computer with the one on the other computer, since that would only result in losing whatever data was entered on the other computer.
Got it. This is one of the benefits of Apple’s .Mac. With a .Mac account you can synchronize Address Book contacts, iCal calendars, and Safari bookmarks. And because this data is synced to the Web, you can update it even when you’re hunkered down in the cottage or on the road.
But .Mac isn’t free.
And I like free.
And because I do, I suggest you take a look at Stephan Kleinert and Markus Brand’s free address-o-sync. This handy little utility—which must be installed on each Mac for which you wish to synchronize contacts—uses Apple’s zero-configuration networking technology, Bonjour, to establish a sharing relationship between Macs on a local network. Fire up address-o-sync on each Mac, tell it what you’d like to sync (all contacts or just selected groups of contacts), click the Sync button, and it does what you ask. If duplicate contacts exist that contain different data—you’ve updated a phone number or email address on one of your Macs, for example—you’re offered the opportunity to choose which data to keep.
