    There are no duplicate entries. There is one row for each Host/User combination. But if you do need to remove one, have a look at DROP USER

    Addition to answer

    This query will show you that the empty users actually have a ” name:

    SELECT Host, User, Password FROM mysql.user WHERE User LIKE '';

    This means they can be removed with:

    DROP USER ''@'localhost';
DROP USER ''@'my_name_goes_here-MacBook-Pro.local';

    Do make sure you really want to remove them though. Maybe there are some processes that need them to be there and connect using these different hostnames.
