OS X 10.6's Address Book allows you to configure for "Synchronize with Google", is this a one time synchronization rather than a dynamic one? The sync settings don't seem to stick after you completely quit the app (via cmd-Q) or after a reboot. Google's page offered little explanation of the syncing mechanism. http://www.google.com/sync/mac.html My iPhone is setup to actively synchronize with my Google contact actively. I'd like to do the same with my Macbook Pro. Is that even possible?
