For a list of OS X versions that the MySQL server supports, see https://www.mysql.com/support/supportedplatforms/database.html.
MySQL for OS X is available in a number of different forms:
Native Package Installer, which uses the native OS X installer (DMG) to walk you through the installation of MySQL. For more information, see Chapter 2, Installing MySQL on OS X Using Native Packages. You can use the package installer with OS X. The user you use to perform the installation must have administrator privileges.
Compressed TAR archive, which uses a file packaged using the Unix tar and gzip commands. To use this method, you will need to open a Terminal window. You do not need administrator privileges using this method, as you can install the MySQL server anywhere using this method. For more information on using this method, you can use the generic instructions for using a tarball, Installing MySQL on Unix/Linux Using Generic Binaries.
In addition to the core installation, the Package Installer also includes Chapter 3, Installing a MySQL Launch Daemon and Chapter 4, Installing and Using the MySQL Preference Pane, both of which simplify the management of your installation.
