One user explains the problem on Apple’s forum like this: Essentially, trying to log-in to a Google account puts users through an endless loop, bouncing between macOS and Google’s sign-in page in Safari. On the other hand, the update also seems to include one frustrating bug related to authenticating Gmail accounts through Apple Mail.Īccording to a growing number of complaints on the Apple Support Forums, macOS 10.14.4 breaks the process of authenticating a Gmail account. Apple yesterday released macOS 10.14.4 to the public with features such as automatic Dark Mode in Safari, Apple News+, and more.
