Uninstall MySQL on Mac

Somehow, I either forgot my password, or I did something to mess up my MySQL instance.  it is a development machine, so I don’t really care about the databases on it.  I just wanted to remove it completely from my machine.  I actually had two copies of mysql installed.  One from Mac Ports and the other was the package directly from MySQL for the Mac.
I used the following commands to completely remove mysql from my system.

sudo port uninstall mysql5-server
sudo port uninstall mysql5

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*
