To set up an SSL connection under Windows, open the
      Advanced Parameters tab of the
      Options Dialog window. Select the connection
      you wish to configure, or create a new connection. Use the
      Advanced Parameters text boxes to send options
      to the MySQL client library in much the same way that you would
      pass parameters to the command-line client.
    
      The parameters are essentially the same as those you would use for
      the command-line client, with underscores replacing
      “-” and USE_SSL
      replacing --ssl. See the following example.
    
        The file separator used for path parameters is
        “/” and not
        “\”.
      
      The parameters used with an SSL connection are found in the
      SSL Command Options section of the reference
      manual. For instructions on setting up SSL certificates, see
      Setting Up SSL Certificates for MySQL. Links to
      the different versions of the reference manual are found at
      http://dev.mysql.com/doc/refman.
    
There is currently no provision for creating an SSL connection when running MySQL GUI Tools on Mac OS X.
