Mojave 10.14.4 fails to Authenticate Gmail account

I have now got the Mail app from 10.14.3 and renamed it Mail Old. Copied in to the Application folder and launched it. It works just fine, no issues no lost gmail connections. So go for it.

It's Mail app version: 12.4 (3445.104.2).

Would you be kind enough to post the procedure you used to recapture Mail 10.14.3 and utilize it. I'm totally exasperated with trying all the "fixes" from other users, which haven't worked for me. Your procedure makes sense and I would like to try it on my iMAC. Thanks in advance.

You have to have a backup fro MacOS 10.14.3 !

I'm using SuperDuper to make backup on an external drive.

Plug it in, an go to the applications folder on the Backup drive and copy the mail app to your desktop. Rename it to Mail Old, and then copy it to your Application folder.

Go to the Application folder and double click on Mail Old.

This seems to be working. I pulled a copy of Mail 12.2 (3445.102.3) from a Time Machine backup just prior to the last macOS update, and dropped it on my Desktop. So far, so good .. at least a whole lot more reliable with gmail than 12.4 (3445.104.8)

Tried the procedure using a Mail backup from September 2018. Unfortunately I received an error message window when I clicked on the Old Mail icon. Still open to any suggestions to resolve this frustrating problem, and thanks.

Thank you. That was an easy and elegant solution compared to other suggestions. First time after updating OS I was asked for password in Safari. That worked for that one day. If it happens again, I am one click away until or unless they make an update to the update.

I had this problem also and tried going through the Safari login process but that just looped as others have stated. I just tried going to inbox which showed the wavy line for offline and clicked on it. Entered my password and now everything is back to normal.

Followed your procedure without success. The latest backup I can access was in September 2018 and the Mail version is 11.5. Going through the suggested process, I get an error, suspect your procedure is valid but my old Mail version isn't workable. Any ideas where I can get the 10.14.3 version to try? Thanks for trying to help.

I am having the same issue where I had authenticate all my gmail emails and additionally I am having internet issues. I keep thinking my wifi is out, but it's not. Internet/WiFi stops working and I have to restart the computer. (MacBook Pro 2017). Restarting Safari does not work. And I even tried Foxfire the second this happened and that didn't work either.

I should send Apple a HEFTY BILL for UNNECESSARY lost time, DISRUPTED business interactions, and UNRELIABLE service. Most, if not all Apple users have paid a HEFTY PRICE for our state-of-the-art devices and expect them to 'JUST WORK'. . . along with instructions on how to REMOVE this POS upgrade.

I've had this problem, none of my email accounts would connect at all. I also noticed that Safari had changed to using Yahoo as a search engine despite the preferences still being set to Google. Looking around I found that in the <Advanced Settings> in Safari preferences the SOOCKS proxy was turned on. As soon as I turned it off all my emails downloaded and my search engine seems to be back to Google.

I have also had a problem. Until Thursday e-mails to my gmail account were sending and receiving normally. On Friday I got a message saying "Enter the password for the account “****@gmail.com”. and a box to Open Safari. I did that, entered my password and then got a message from MacOS (Developer info 'account_support@apple.com') saying it wants to access my Google Account to 

"Read, compose, send and permanently delete all your email from Gmail

See, edit, download and permanently delete your contacts

See, edit, share and permanently delete all the calendars that you can access using Google Calendar

View and send chat messages"

At the bottom it asks me to "Make sure that you trust MacOS. I wondered if this was some kind scam but it looks as if it is an incompatibility issue.

I have the gmail app on my iPhone so am getting my gmail there and I can also pick up my gmail in Safari. The problem is that I can no longer take them out of the inbox and save them to files like I can in Apple Mail. I ma not familiar with Spark. Is this an alternative e-mail app that can be used with the MacOS?

Are you or anyone reading this had issues with the internet as well? I had the gmail issue, but once I put in my passwords it worked. But the internet, it stops working from time to time and I have to restart the computer for it to work again.

I had the same issue of Mail logging out of gmail, and tried some of the suggested workarounds to no avail.

SOLUTION: What worked for me is to copy the Mail app version from my backups before the 10.14.4 update, and put in utilities folder. I launched from utilities folder and has been working ever since with no problems.

Just make sure you quit out of Mail app, and copy the app from your Time Machine backup drive (Not from the Time Machine app).

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.
