Error 400 invalid_request Gmail on Mac | How to Fix Apple Mac Mail
Apple Mac Mail on macOS Sierra and macOS High Sierra is giving error 400: invalid request on Apple Mac Mail.
The error 400: Invalid_request means that Google is no longer trusting Apple Mac Mail application on macOS Sierra, macOS High Sierra, and earlier versions of macOS from macOS Lion to macOS El Capitan, on older Apple Mac computers.
With macOS Lion, macOS El Capitan, macOS Sierra, macOS High Sierra the problem cannot be fixed, repaired or resolved, as the Apple Mac Mail application does not meet or now support the minimum computer security requirements that a Google Gmail account needs.

But Apple and Google consider this a security risk, however, if you are a home Apple Mac Computer user and you do not have sensitive information and you just need to get email using Apple Mac Mail on an older Apple Mac Computer, at Keith Thomas we can help you setup Apple Mac Mail to work with Google Mail.

Will Apple or Google Fix the Error 400 Message on macOS Mail when trying to add a Google Gmail account or after a Google Mail Password was Reset or Updated?
No. Apple and Google will not fix the Error 400 which is mainly due to Google updating their IT Security to not allow any devices, that do not support a more modern security method to be used. However a work around is possible if you need to use a Google Email or Gmail account with earlier versions of macOS El Capitan, macOS Sierra, and macOS High Sierra. But this will make a Gmail account or a Google Account much less secure to use.
