Mac completely remove MySQL

How to completely uninstall MySQL and delete it from your Mac (including all databases) do the following:

• Open terminal window
• Use mysqldump to back up your database with a text file!
• Stopping 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 especially important, otherwise you can't install an older version of MySQL, even if you think you've completely removed the new version! I hope we can help you!
