In my case  the file did not exist  In MySQL Workbench I went to OPTIONS FILE and found some default values  I clicked apply  It asked for permission  It then created the my cnf file under  etc  However  it is very important to keep in mind that the first time you click  apply   you do not make any changes to the default configuration  Once the file has been created  you can make changes which will be applied when you click  apply   Otherwise you will not be shown the apply button when you make changes

If you are using macOS Sierra and the file doesn t exists   run   mysql --help or mysql --help   grep my cnf   to see the possible locations and loading reading sequence of my cnf for mysql then create my cnf file in one of the suggested directories then add the following line    mysqld  sql mode   STRICT TRANS TABLES NO ZERO IN DATE NO ZERO DATE ERROR FOR DIVISION BY ZERO NO AUTO CREATE USER NO ENGINE SUBSTITUTION  You can sudo touch   preferred-path  my cnf then edit the file to add sql mode by   sudo nano   preferred-path  my cnf   Then restart mysql  voilaah you are good to go  happy coding

This thread on the MySQL forum says      By default  the OS X installation does not use a my cnf  and MySQL just uses the default values  To set up your own my cnf  you could just create a file straight in  etc     OS X provides example configuration files at  usr local mysql support-files    And if you can t find them there  MySQLWorkbench can create them for you by    Opening a connection Selecting the  Options File  under  INSTANCE  in the menu  MySQLWorkbench will search for my cnf and if it can t find it  it ll create it for you
