Mojave 10.14.4 fails to Authenticate Gmail account

ok was about to do that. :) Let's see if it works.

edit: And it works! Thanks much.

You're welcome.

How can I return to previous OS system so I can get mail on new MacBook Pro? So frustrating - glad I found an article about it so I don't waste more time. When will Apple fix this?

Thanks - it worked. now to rename a couple of email files that are misnomered.

I am see people post 13.0.1. update ,but i am not seeing this in my updated. ****** as this put my mail out of action, and I has to do a convoluted workaround.

Worked for me too.

I have tried doing what Lazy-Ants suggested but I am still having this issue. So annoying. It is now affecting my calendar as well as my Mac Mail.

I have been tormented by this for months and tried every solution posted here. This was the only thing that worked for me. Thank you so much for sharing!

This worked for me! Took a while with Apple on the phone, but my account is working again.

email address mismatch

Since update to 10.14.4 iTunes Match fails to update iCloud Music Library too! Including the issue referenced in this thread. I’m adding to the thread about update fails. I don’t feel like starting another thread about iTunes Match. Also, I’m not looking for answers.

Apple Support confirmed they know about the issues and a “Fix” is being finalized.

This happens because when you log in you receive a token and a refresh token. The token is only valid for a brief period of time (something between 12 and 24 hours). Then it is not valid anymore and you need another one.

The OS then goes to Google with the refresh token, and then Google gives you a new pair of token and refresh token, and the operation proceeds.

What happened is probably related to how this token handled and/or stored, which basically means our tokens expired, iOS/macOS tried to refresh it, and the problem happened, requiring us to log in again. And the bug is on the token so no matter what we try, Google refuses the token forever.

This is the same process that happens when you change your password, and allows you to be authenticated for a good period of time while still allowing you to invalidate other log in sessions.

Same problem. Writing to save people time who might be trying to fix this or find a workaround. I have been in phone contact with Apple upper level tech support. Since updating to 10.14.4 I cannot connect to Gmail (I can access iCloud mail) using the native Mac email client though I can access Gmail using the Thunderbird email client on my Mac. I can access Gmail on my iPad and iPhone.

Here is what upper level Apple Tech suggested. I tried everything. Nothing helped. They offered to revert me to 10.14.3

Deleted the Gmail account and reinstalled.

Reset my SMC and my Pram.

Set up a new administrative account and tried to access Gmail on that account using the native Mac email client.

Reinstalled MacOs 10.14.4

Again, none of this helped. I filed a bug report. If others did the same it might get Apple's attention sooner.

Both of my gmail accounts are pretty old. The GSuite one doesn't work even after changing the password. The regular Gmail one is, knock on wood, still functioning.

At least in changing the password I got the prompt to "allow" Google to do certain things, but it still doesn't work after that.

I don't think there's any difference between the lightning bold and the "Login Failed" link. Both fail here.

In my case the whole authentication system appears to be broken.

I can only login into the MacOS user account after a restart. Even then it takes about 7 minutes.

I cannot log into my the Appstore or authorise admin privileges for removing an application etc.
