  1. You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. This precautionary statement does not apply to the normal installation of application software.

There are two ways to update to Mac OS X 10.3.3: Software Update and Standalone Installer.

Software Update Installation

Because some updates are prerequisites for others, you may need to use Software Update more than once to get all available updates.

Standalone Installer

An installer is also available from Apple Downloads.
