Apple mail does not sync with gMail

Ok, after reading your comment about how good Thunderbird was, I went and downloaded it. I love it!! The layout and customization of it are much better than Airmail, and it's working flawlessly.

I wish I had tried it earlier—I could have saved myself a lot of aggravation. Thanks for the tip!

I may be detecting a pattern in what may be causing Apple Mail to hang and, even more importantly, how to unblock it. My major annoyance is when my Apple Mail Inbox shows messages as unread when they should be deleted or shown as read because I have read/deleted them on my iPhone. This problem seemed to start once I added other accounts besides iCloud and Google. Almost every time, when I open the Connection Doctor window, one of my other accounts has a red status. In my case it is a GoDaddy IMAP account and Mail wants the security certificate to be verified or needs the password to be entered again. Once I have all green status lights in Connection Doctor, after a few minutes, Mail updates correctly.

Has anyone else encountered this?

I only have one account (Gmail) and I see the same problems you mention (mail not marked read or deleted after I read or delete on iPhone or iPad).

How is Gmail configured on the mac, POP or Imap?

Csound1L My gmail is IMAP

cationic: Do you seen any red status dots in the Connetion Doctor?

Unless the red dots are on the Gmail account they are not relevant.

NormdVA: sorry, I'm not familiar with Connection Doctor. And, I gave up un Apple Mail, I am using Airmail now.

I did have GMail set up as IMAP in Apple Mail

In my case the situation got worst with the update. Sometimes syncs, sometimes doesn't. Once a group of mails doesn't sync, they remain at the inbox even if the full mailbox gets again in sync.

I'm now trying Airmail!

I'm trying Postbox. Seamless transition from Apple mail.

cripoli - please try this - it worked for me.

Mail->preferences->accounts

Look at alias on icloud mail account. Set it to the alias ending with @icloud.com. My alias was set to the @me.com account.

Fixing icloud acct somehow fixed my gmail issue. My gmail began to download immediately after this change and has been working well for 4 days now.

Please let post if it works or not.

I am unclear what an iCloud email alias has to do with Gmail, could you explain?

I'm not wasting any more time with Apple Mail. This is is ridiculous. I have moved to Postbox and can't be happier. When and if Apple fixes Mail, I may reconsider, but Postbox plays nice with icloud, gmail and other IMAP accounts.

Neither iCloud alias or the Connection Doctor did anything to fix my sync issues. Completely frustrated.

That is because iCloud aliases have nothing to do with Gmail, and Connection Doctor is a diagnostic tool, not a fix it tool.

What did the Connection Doctor report say

Connection Doctor had some issues with other email accounts, corrected those, restarted Appl Mail and still no success.

I now deleted my gmail account from Apple Mail and then re-added it but through the Internet Accounts section of OSX settings. This produced a really strange behaviour.

Running a test of sending from my iphone to the gmail account, from another account that I have, I saw the message show up in Apple Mail, this is good. I then went into the message from my iphone and then out so it would now show as read. Here is the strange part, the message was then removed completely from Apple Mail! It is not in the junk mail folder but it is in my Trash folder! On my iPhone it still shows it as being in the Inbox!
