I found a solution to this!
- Sign into the Google Account you want to add to Apple Mail
- Go to Settings, and select Security
- Select Two-Factor Authentication, and set this up.
- Once done, at the bottom, you’ll see App Password. Select that.
- Name the app (I used Apple Mail), and generate 16 character password.
- Copy that password
I’ve seen these steps before, and tried and tried to get someone to answer my question of “now what?”, as I couldn’t find anywhere to use it.
Then I tried this and it worked:
- Open System Preferences, and select Internet Accounts
- Scroll the list up, and select “Add Other Account
- In the list, select Mail account
- Enter the Gmail address in “Email address:”
- Paste the 16 character password in “Password:”
It took a few seconds, but then the Gmail account showed up in Apple Mail!
You’ll notice it isn’t displayed as a “G” account in the list of Internet Accounts, but who cares?! It works!
I hope it works for you too!
