Apple Mail no longer retrieving GMail

[MagnusVonMagnum]

Since GMail just "upgraded" their accounts with new features in the past several days, I've discovered that Apple's mail program has failed to retrieve my mail messages (last message is dated 11/28/13). If I run Gmail from a browser or use Thunderbird (which I haven't run in some time), they show up just fine so I can only surmise there is a bug in Apple's Mail programs still in Mavericks. I guess I'm going to move back to Thunderbird again, at least until it's fixed. And this started long after Apple posted their previous Gmail fix a couple of weeks ago.

Edit: I found if I quit the Mail program and restart it then it starts getting the messages again. The problem is I have no idea if it will do it again. It makes it seem unreliable now.

I had a friend with what may be a similar issue.

Her 10.8.5 iMac was fine; her iOS 7 iPhone was fine; but her 10.9 13" MBP had simply stopped showing new emails from gmail and ntlworld, who incidentally use a gmail back end.

I checked all settings were identical between the two Macs and the Connection Doctor on the MBP was showing four greens. Really frustrating. In her case, restarting the Mail client didn't help.

Then I noticed her Apple ID was linked to a yahoo.co.uk email address, although that email wasn't in use on her MBP. So, to aid diagnosis, I set her up with an iCloud email address, linking that to her Apple ID and enabling email.

As soon as the iCloud address began working on her MBP, the two gmail accounts started retrieving emails from their respective servers.

Problem solved, in her case, although I have no idea why the gmail accounts should effectively be disabled without an iCloud address present in the client.
