Uninstalling MySQL on Mac OS X Leopard

To uninstall MySQL and completely remove it (including all databases) from your Mac do the following:

  • Use mysqldump to backup your databases to text files!
  • Stop the database server
  • sudo rm /usr/local/mysql
  • sudo rm -rf /usr/local/mysql*
  • sudo rm -rf /Library/StartupItems/MySQLCOM
  • sudo rm -rf /Library/PreferencePanes/My*
  • edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
  • rm -rf ~/Library/PreferencePanes/My*
  • sudo rm -rf /Library/Receipts/mysql*
  • sudo rm -rf /Library/Receipts/MySQL*
  • sudo rm -rf /private/var/db/receipts/*mysql*

The last three lines are particularly important as otherwise, you can't install an older version of MySQL even though you think that you've completely deleted the newer version!
