Several people are experiencing issues with Gmail (especially G Suite) email accounts in Mail on Mac. It seems that the Mail App is not working as expected for some Gmail users. More specifically, some Gmail users have said that after installing the macOS 10.14.4, and launching the Mail app, some Gmail users are asked to authenticate their email addresses. They get a notification saying:
Gmail Desktop Notifier. The Gmail Desktop Notifier is one of the more popular methods to receive desktop notifications for Gmail. It is also one of the original notification clients available once notifications were released as a feature on Mac OS. Gmail Desktop Notifier is a nice, small, unobtrusive icon that sits in your menu bar.

“Enter the password for the account “(null)”: Google requires completing authentication in Safari.” This takes users to a Google web login form. However, shortly after authenticating, the Mail app asks for authentication once again, and again, as the process does not stick and goes into an endless loop.
Please note that we contacted Apple regarding this issue, and we were told that Apple is currently working on a fix.
In the meantime, you can try the following fixes:
1– Changing your Gmail account’s security settings may fix this problem. Open Google’s My Account site (https://myaccount.google.com) and click Security (On the left navigation panel) and then scroll down and find the “Less secure app access” section and turn this on (note that Google recommends this OFF).
