After 10.14.4 my hotmail and ntlworld mail accounts will not login. Have checked passwords and theses are the same ones that still work on the iPad and iPhone . But re-entering on iMac says "unable to verify account name or password". The question "mail for mac will not accept my password" has an answer about "app-specific passwords" and talks about 2-level authentication . What should I do ? Do I have to make new passwords for hotmail and ntlworld? Or is there a bug fix coming? Help!!!!
