I wrote an blog post back in March explaining how iPhone and iPod Touch users could sync Address Book with Google and Yahoo on Leopard. Well … Snow Leopard removes the iPod Touch/iPhone requirement.
Here’s how you do it.
Open the address book application
Open the address book’s preferences
Click the accounts tab
Check the synchronize with Google
Click the configure button.
Fill in the information
Let the address book do its thing.
Done.
