I am trying to add a Google account using System Preferences > Internet Accounts.
I already tried the following.
able to reproduce this in 10.12.3 and 10.12.2.
disabled OTP, same issue
able to reproduce in Macbook Air and Macbook Pro
same issue with both Gmail account (tried two) and Google Apps account
I am not using any iCloud
it appears to be similar to this issue but the fix does not work: Can't login with Google using Internet Accounts
adding LinkedIn works
I already tried to VPN to California and Singapore to check if something is wrong with Google mirrors
creating a new user account and adding the Google account from there, same issue
as advised by Apple Support tried https://www.google.com/accounts/UnlockCaptcha
It gets stuck right after a successful login. I took a screenshot.
Anybody experiencing the same issue?
