Users of Apple’s new macOS 10.14.4 report that it prevents them from logging into Gmail and G Suite accounts through their Apple Mail apps.
The alleged bug, which apparently does not affect all users, breaks the process of authenticating a Gmail account, media reports state. Apple introduced macOS 10.14.4 on Monday.
Here is how one user describes the problem on the Apple support forum, according to 9to5Mac:
“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.”
According to Apple Insider, another writes: "Just update[d] 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."
"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."
9to5Mac reports that macOS 10.14.4 offers such feature automatic Dark Mode in Safari and Apple News+.
