Note:

• It is recommended that you back up your system prior to installing any updates.
• The installation process should not be interrupted, even if the progress bar remains unchanged for several minutes. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Support Downloads to update.
• You may experience unexpected results if you have third-party system software modifications installed, or if you've modified the operating system through other means. (This does not apply to normal application software installation.)
• If issues occur during installation--for example, if Software Update quits unexpectedly--please see this article.
