Where is my my.cnf file located?

The configuration file "my.cnf" of MySQL can be found here: "/Applications/MAMP/tmp/mysql/my.cnf". Please note: Editing this file does NOT work as it will be overwritten every time MySQL is restarted by MAMP PRO with a "my.cnf" file that is created from the MySQL template. You must edit this template (menu File > Open Template > MySQL (my.cnf) > 5.7.30) to modify the MySQL configuration. Manually adding "my.cnf" files to other locations is not recommended. Every configuration aspect can be handled with the MySQL template.
