Question: Mojave 10.14.4 fails to Authenticate Gmail account

Just update to Mojave 10.14.4 and now Apple Mail will NOT connect to one of my Gmail accounts.


This issue is UNIQUE to Apple Mail as I can access the Gmail account using Spark on the same computer without issues.


This issue is UNIQUE to Mojave 10.14.4 as it did not exist with 10.14.3 and it does not exist on another computer running an earlier version of Mac OS X.


The issue puts me in an endless loop. I get a notification "Google requires completing authentication in Safari." This takes me to a Sign in dialog where I enter email account and password. Password is correct and accepted, after which I'm back in the loop again asking to enter Google Password.


If I login to my Google account in Safari I can see the recent events that I signed in without any problems on this Mac, but Apple Mail does NOT connect and I am back in the endless loop.


Oddly I can add events to the Google Calendar for the account so apparently something is amiss strictly with Apple Mail.


Suggestions?

iMac 27" 5K, macOS 10.14

Same issue here;


• GMail account works fine

• G Suite account does endless authentication loop

• Issue only on MacBook Air, on iOS devices and Mac mini it works fine

• It worked for a few hours after 10.14.4 update then suddenly refused the next morning

"At the moment the only fix is to delete the account and add it in manually as an IMAP account"


"I tried that; unfortunately won't work unless your organization admin allows authentication outside the Google site login and I believe that's the default. "


I am not sure about that - I am the admin of our organisation and it works fine on the defaults. The app specific password still uses Google to authenticate?

I have exactly the same problem. Regular free Gmail accounts are working fine after a request to authenticate (again). However, all G-Suite accounts are looping back to require the authentication process again and again and it doesnt work.

Tried the same with Spark and is working fine as it seems.

This happened on all computers updated to MacOS Mojave 10.4.4 and no others !!

I tried the less secure option, I tried to deactivate 2 Step Verification, I tried with an App password, etc. Nothing works so far.

At very beginning just after upgrade all my G Suite accounts works well but suddenly some G Suite account with "Login failed" error after system sleep.


Follow the step by step to re-authenticate Gmail account - Just after input 2FA code, it should redirect to "Allow" to click on the "Allow" button to complete authentication process but it just close Safari itself - endless failed loop. 😡


Turn off and on the 2FA authentication of Google account is NOT a good idea, it will cause iOS device login failed and no way to bring it back.


After spends few hours on it I use the workaround method to bring back email (only) is using IMAP4 & SMTP with "Google App password" (temporary), drawback is cannot access Contact & Calendar anymore.

The new macOS Mojave 10.14.4 and iOS 12.2 is terrible, remove and add Gmail back never works. Hope my still working G Suite without problem in coming next few days.


Planning restore from Time Machine back to previous macOS version on coming weekend.

Same problem here but it seems completely random; I have no problems on iOS12.2 but on MacOS 10.14.4. But here only on the iMac and not the MacBook. Also, of my 10 Gmail accounts, 'only' four show the problem, the others log in fine. The four accounts affected are all regular free Gmail account. My G-Suite accounts work fine...

I hope this will be fixed soon!

Same problem for me. MacOS 10.14.4, MacBook Pro 15" 2008.


I have 2 accounts:

1) a new corporate G Suite account (corporate domain) set-up within the last 6 months - this is *working* after a single safari authentication.

2) a much older G Suite account (personal domain) - this is *broken* and I am stuck in the authentication loop. This account is a free "grandfathered in" one from when Google Apps for Domains was free.

Having the same problems too.


Rather than mess around with IMAP settings, I've loaded Spark in the short-term, which is working fine. I will revert to Apple Mail once they have fixed this issue, which should be an urgent priority for them. I've been using Apple Mail too long to go over to another mail app for too long!

Same issue with me. The normal gmail account is working with Mail, but the gmail suite account not, just an endless authentication loop. I spoke to Apple, they are aware and working with Gmail on a fix, but I was advised to contact Gmail and see if they can do something. Very disappointing from Apple!
