I found a solution for this.


  • Delete your Yahoo! account from Internet Accounts.


  • Go to your Yahoo! account in your browser.


  • Click on your account on the top right.


  • Click Security.


  • Click Generate and manage app passwords.


  • Enter "Mail" when prompted for an App.


  • Copy the password Yahoo creates.


  • On your Mac, go to System Preferences > Internet Accounts.


  • Instead of clicking Yahoo!, click Add Other Account.


  • Click @ Mail account.


  • Enter your Yahoo! email address and paste the app password you just generated on the Yahoo! website.


This worked for me and I now have my Yahoo! emails actively coming into the Mail app on my Mac.
