I need to install older version of mysql server on mac os, but I have a newer version.

I tried to remove this newer installation (5.1), but when start old version install (5.0b) message "MySQL 5.0.51b-community for Mac OS X can't be installed in this disk. A newer version of this software alrady exists on this disk".

I can't recognize problem, because I remove all data of previouse install, but installer says no.

Mac OS version 10.6.

You can use the built-in utility pkgutil to remove the package receipt:

sudo pkgutil --forget com.mysql.mysql

On Snow Leopard I had to additionally kill mysqld and did

rm /private/var/db/receipts/com.mysql.*

sudo rm -rf /Users//Library/StartupItems/MySQLCOM sudo rm -rf /Users//Library/PreferencePanes/My* sudo rm -rf /Users//Library/Receipts/mysql* sudo rm -rf /Users//Library/Receipts/MySQL*
