How to Sync Gmail's "Other" Contacts with OS X Yosemite (Mail.app and Contacts) and iOS Mail I'm trying to get Mail.app on OS X Yosemite to autocomplete contacts on my Gmail "Other" group - i.e. the contacts google creates for you once you've sent them an email.

I have a Google "Internet Account" setup in OS X, which syncs Google's contacts, but only the ones in my Gmail "Address Book", which does not include the earlier "Other".

If I try to set up a CarDav account in Contacts with my gmail credentials it tells me it's a duplicate, and if I try to add some extra dots to my email, it will create my account, but immediately turn it into a Google account as opposed to a CarDav.

I would ideally like to achieve a similar setup on iOS, having the Gmail "Other" available for autocomplete on iOS Mail

Any pointers would be greatly appreciated
Mail.app and Contacts.app have no access to the "Others" group from gmail... 

however, if you compose all your gmail account messages in Mail.app on iOS or OS X instead of the gmail web client, they will autofill any addresses you have previously sent to.
