Make MAMP PRO not ask about passwords on service restart

Change your default MAMP password from ‘root’ to something more useful:
/Applications/MAMP/bin/mysql4/bin/mysqladmin -u root -p password newpassword


Edit the following files:

• /Applications/MAMP/bin/phpMyAdmin-X.X.X/config.inc.php

  $cfg['Servers'][$i]['password'] = 'newpassword'; // change root to your new password


• /Applications/MAMP/bin/mamp/index.php

  $link = @mysql_connect(’:/Applications/MAMP/tmp/mysql/mysql.sock’, ‘root’, ‘newpassword‘);
  

• /Applications/MAMP/bin/stopMysql.sh

  # /bin/sh
/Applications/MAMP/bin/mysql4/bin/mysqladmin -u root -pnewpassword –socket=/Applications/MAMP/tmp/mysql/mysql.sock shutdown
