While you can change the installation location, the software installs by default in the /usr/local/mysql directory.

That’s required because the database is installed with an unsecured anonymous and root account. There were a couple shell syntax tricks beyond the instructions and then you need to configure database. I downloaded the Mac OS X, Version 10.6 (x86, 64-bit) version for this installation. You can refer to this XCode installation and configuration post for those steps. Mac OS X Mountain Lion (10.8.*) need to install XCode and Command Line Tools before installing MySQL.
