- Is your goal to have access to the contacts from each Google account, but to keep the contacts from each account separate?
- In this situation, I would suggest syncing your primary Google account with Mac using this app. Add any additional Google accounts by going to your Mac System Preferences > Internet Accounts.
- The account you add to your Mac System Preferences will not have groups, but the contacts in that account will be kept separate from your other accounts.
- Otherwise, if your goal is to create a 3-way sync, with the same contacts in both Google accounts and your Mac, follow these instructions:
To create a 3-way sync, I would suggest syncing your 1st Google account with this app, and your 2nd Google account using this app's sister product ("Contacts Sync for Google Gmail" or "Synctastic").
Alternatively, if you have multiple Macs, you can install this app on each of your devices at no additional charge, and sync your primary Google account with iCloud from your primary Mac, and your 2nd Google account with iCloud from your other Mac.
Alternatively, you can toggle between Google accounts from this app, and sync each one individually.
