macOS 10.14.4 G-Suite bug is fixed

The previously reported bug that caused a login loop for Google-hosted G-Suite accounts has been fixed, presumably on the server side.

The bug was first introduced in macOS 10.14.4 beta. Originally the bug affects any Google accounts with Two-Factor-Authentication (2FA) turned on; Gmail and G-Suite altogether. When macOS 10.14.4 was released, only G-Suite accounts with 2FA were affected. iOS 12.2 was also affected by this bug.

We checked on Saturday morning, March 30, 2019, and found out that the issue was fixed. Assuming that it was fixed on the server side by Google.

A lot of businesses and educational institutions are using G-Suite.

With the release of macOS Mojave 10.14.4, another bug that was originally introduced in 10.14.4 beta. This bug also presents in macOS 10.4.5 beta, iOS 12.2 and iOS 12.3 beta.

Google-hosted G Suite account with Two-Factor Authentication enabled will not be able to log in properly.

When adding a G Suite account you will get a message:

Google requires completing authentication in Safari.

In macOS 10.14.4, to authenticate Google Accounts, Safari opens in Private Browsing Mode.

This bug had been reported multiple times by Apple Developers and Beta testers since the release of macOS 10.14.4 beta 1.
