macOS Sierra Internet Accounts Google login stuck
Solution 1:
Combining part of your solution and part of the solution from Can't login with Google using Internet Accounts, I got mine to work again by:
- Opening Keychain Access > login and searching for 'google', then deleting all the 'accountsync' and 'oauth' entries. The resulted in my Google account being removed from System Preferences > Internet Accounts.
- Completing this: https://www.google.com/accounts/UnlockCaptcha
I was then able to go to System Preferences > Internet Accounts and add my Google account back. It showed the spinny wheel on the gray screen for a second, then disappeared and I was in! Mail and Calendar show my Google data now.
I have 2-factor auth enabled.
Another solution to this would be to login to your GMail account via another program that access's macOS's shared accounts, like Calendar.app.
Solution 2:
I had the same issue, here's how I solved it:
- removed all internet accounts (including icloud and game center).
- double-checked I was logged out from my apple account
- shut down computer
- start computer
- login to apple icloud again
- login to google again
I tried deleting all passwords from keychain: no change.
Solution 3:
I found that if you have a default browser other than Safari you will face this issue.
- Solution one: changing default browser to Safari
- Alternative solution: When you see it stuck, start Safari and it will magically work.
