I had an old instalation of MySQL but it wasn't working very well.. so i googled how to completley remove it and found this:

and then did:

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

And now i'm getting this on a new install:The Instalation Failed

i also ran this commands:

    sudo rm /var/db/dslocal/nodes/Default/groups/_mysql.plist
sudo rm /var/db/dslocal/nodes/Default/users/_mysql.plist
sudo rm /var/db/receipts/
sudo rm /var/db/receipts/com.mysql.mysql..plist

any help on this?

Many Thanks, Mr. Nizzle.

You may try to remove manually everything again, and to create the mysql user by yourself using this guide.

Then try to perform the installation again.
