​I can’t create new Contacts on my Mac

(Contributed by Jim Coulston)

After upgrading to Mac OS High Sierra, I noticed that I became unable to create new Contact records on my Mac.

I’d be part way through creating a new Contact in the Contacts app, and the screen would suddenly refresh to an existing Contact - and the one I was creating just vanished!  If I did get to finish entry (for example, if I just entered a first and last name and the Done), the new Contact would appear in the list briefly, but disappear again after a few seconds.

At first, I thought I was hitting some strange key combination, or that I was doing something else wrong.  However, nothing I tried seemed to work.

The problem persists today.  I can edit existing Contact records, but I just cannot create them on my Mac.
 
We use a Gmail account for our shared business contacts and the issue seems to be related to Gmail accounts.

It seems I’m not alone in having this problem. I checked the Apple support forums and there’s lots of reports of the same issue.  Here are some suggested work-arounds.

• Create new Contacts using your iPad or iPhone and these then sync back to the Mac, where you can then edit the Contact Card to your heart’s content.  (Maybe not the most elegant solution, but this is the option I have been using - and it saved my sanity when I discovered the problem.)
• Create the Contact first as an iCloud contact on the Mac, copy that new Contact card to the Gmail account, then delete it from iCloud contacts
• Disconnect from the internet temporarily, add the Contact, then reconnect.  This seems to avoid the problem, as it seems that sync'ing wipes out what have created.

None of these options are ideal, but at least I have a work-around until Apple and/or Google get around to fixing this annoying problem!
