Answer 1

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 2

Same question asked here, at roughly the same time it would seem. I posted over there.

Answer 3

Try running also

sudo rm -rf /var/db/receipts/com.mysql.*

Answer 4

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.
