Answer 1

Test finding all files and folders with "mysql" in their name, take a look at them and see if they must be deleted as well.

Use the following command to find all the files.

sudo find / | grep -i mysql

You can scroll through the output if you put | less at the end (it won't show anything up until it finds something, just so you wouldn't think the command failed.) :-) You can write it as follows.

sudo find / | grep -i mysql | less

To remove the files/folders, you will have to run the following command (-f means force so you won't be able to restore the files and you won't be asked for a confirmation before they are deleted):

sudo rm -rf /path/to/file/or/folder

Hope this will be of any help.

Answer 2

I believe you can essentially just delete the /usr/local/mysql-Version/ and unlink the /usr/local/mysql directory. Getting rid of the system pref and the start up item might be harder, but I didn't install those so I can't help there.

Answer 5

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*

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

sudo pkgutil --forget com.mysql.mysql
