I have set up my Mac Address Book to sync with my Google Contacts. I have created some groups in my Google Contacts and I have created some groups in my Mac Address Book. These groups are not identical. After a period of time shouldn't they be?? What should happen in such a situation? How is the best way to manage Contact groups? I have an iPhone, and was looking at apps to create contact groups on it, but held back as I seem to be in a mess with my Mac and Google syncing, without adding to the confusion. Thank you for any comments or suggestions.
