Need to sync contacts with Google using Leopard 10.5 Address Book?

Let me first start by saying that It is not easy.  Does not even make sense that you have to have an iPod Touch or an iPhone to make this synchronization possible.

Some of the forums that helped me figure out this issue:
  • Apple forums
  • LifeHacker

Since the iPod Touch that I used did not do the trick, I was forced to setup the synchronization not only with Google but also with Yahoo in order to have the “Sync Now” available.
