Mojave 10.14.4 fails to Authenticate Gmail account

After adding my voice to the chorus of those having issues, I’ll now add my voice the the chorus of those for whom it is fixed without doing anything. At approximately 17:45 EDT I tried again after seeing some notes in this thread that for some it worked without any Charles or other effort, and I was able to sign in with Safari and Mail says everything is ok now.

I still have issues with my 2 Gmail accounts on my iMac but strangely not on my Mac Book Air !?!

The connection is lost it my iMac goes to sleep and I have to shut down Mail app and launch it again. Try to reconnect does not work.

I had the same issues not working on one G-Suite Account but working on another G-Suite and Gmail account. It seems to be working for me as of today 01 April 2019 at 9:00am CAT. I was asked to re-authenticate and used the SMS authentication code option.

Can you provide more detail on the procedure you suggested. In my keychain I have "Google Authentication Token" listed twice. Is this what you are referring to? What do you mean by authorise, profit? I'm in Rome, Italy and my iMAC is in Italian but I'm still experiencing the same problem related to the update. Thank you

I've also had this issue since I updated my OS to Mojave 10.14.4. But finally I was able to have it fixed.

I found this google link https://support.google.com/accounts/troubleshooter/3178296?hl=en and after answering the questions there, I ended up seeing the following text with this magic link https://www.google.com/accounts/displayunlockcaptcha:

To grant access to your Apple device, go to your web browser and follow the instructions to allow a new application to access your account.

Clicking on the link and following the steps, I got to a page stating:

Account access enabled

Please try signing in to your Google account again from your new device or application.

At this time, I went back to my Mail app and tried to authenticate again using the account with the issue. So I was redirected to google's login page on Safari where I had to put my email/password and login. After that I went back to Mail and finally no dialog showed up asking me to authenticate again as before. So I went to Mail settings and confirmed the account status was online. But to make sure, I closed and opened the Mail app, checked the account status again, exchanged some emails and no issues so far.

Seems to be fixed now, thankfully. Spark does some pretty cool things, but I rely pretty heavily on the integrations between the native Mac OS apps. I also kept losing threads in it.

I did end up deleting and re-adding all of my accounts, just to start from a clean slate, but I didn't have any issues adding the Google accounts this time.

Yes I notice Mail now loses connection to all accounts after waking Mojave from sleep. Press the bolt icon to connect accounts and accounts get back online.

Also, anyone else notice banner notifications for Mail now don't work in 10.14.4? Noticed it today.

I don't believe Apple is interested in fully resolving this issue; this is an indirect "incentive" to move some of the gmail users to alternative "partner" services, or icloud. This is nothing more than an experiment, in the likes of the one that Facebook has done to test the loyalty of its users.

This has been fixed.

Try to re-authenticate again using the normal method and see what happens.

Set up the account using the "Google" selection when adding the account, not "Other" and entering IMAP/SMTP settings manually.

I've reached my limit with Apple's software "solutions." I'm getting a different mail client, just as I've done with many other Apple products. I can't rely on them anymore, and frankly, have lost confidence in them for some time now. Sad.

I have a similar (but not quite the same) problem. Mac Mail decides (for reasons known only to the gods or a developer's typo) that my gmail account is offline. If I quit or force quit Mail, and restart it, a miracle happens, and mail recognizes that gmail is alive (which is has been the whole time). It's far beyond "annoying" at this point. Either Mail, or some interaction with 10.14.4 has a substantially irritating bug.

Yes, I think you're right. I'm going to avoid minimizing Mail and check it out, but that seems right. If I minimize Mail and don't go there for some period of time, or close the lid on the MacBook Pro and come back some time later, it has invariably decided that gmail is offline.

This might have coincided with with G+ shutdown, as from what I gather, GSuite authentication is tied to G+ APIs. So, authentication was transitioned from G+ to another method, and it wasn't a 1 to 1 transition, and it was a gradual one. This was indeed poor coordination between the companies, and for the most part Google is to blame. I anticipate that Apple switched to new APIs a bit too early, and Google wasn't prepared. Second, there are some inconsistencies, as if you have backup email for your GSuite account, for some reason, that's what's going to be picked up by Apple, as opposed to your actual email; one of my Gsuite accounts doesn't even list my primary account, just aliases. These are all bugs from ongoing shutdown of G+.

Grant-Y, this just happened to me also. I've been keeping an eye on this thread and waited to update to 12.2 and 10.14.4 until I saw that it was resolved for numerous people (3 days ago). My account is personal not gsuite, and updated just fine with a few authentications. I then wanted to have 2FA on my account, so I initiated that 2 days ago after the OS updates and the gmail account performing as needed. Then today after my computer had slept numerous times without issue, I noticed the 'lightning bolt' next to my gmail account. Tried using the Mail/Mailbox menu to bring it back on line, but nothing happened, not even an error. So I restarted Mail, and problem seems fixed. Please let me know if this problem persists for you and I will do the same.

Sure. I had to reauthenticate gmail just once — right after installing 10.14.4.

The nagging issue of Mail losing touch with gmail, as I think about it, has been around for a while — only not nearly as bad as it is now. I know that very occasionally I had Mail try to convince me that gmail was offline, always after bringing up the screen after being minimized, and had to restart Mail. But now the issue has become MUCH worse. If it matters, my machine is a Fall 2018 MacBook Pro,

By the way, I don't use GSuite or any other google service other than gmail.
