About the Mac OS X Server 10.4.11 Update

This software updates Mac OS X Server 10.4.x to version 10.4.11. This update is available as either a "combo" or "delta" update installer, for either PowerPC-only or Universal Mac OS X Server 10.4.x systems, and can be obtained via Software Update or standalone installer (manual download).

Important: Read before installing

• 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.)
• The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.
• It is recommended that you backup your system prior to installing any updates.
• If issues occur during installation--for example, Software Update quits unexpectedly--please see this article.

Installation

To update your Mac to Mac OS X Server 10.4.11, use Software Update or the standalone installer. You only need to use one of these methods to update your computer.

Software Update

Software Update, located in the Apple menu, will automatically check for the latest Apple software using the Internet. (Software Update might have linked you to this article to learn more about the update.) If your computer is not up to date, software updates for your computer will appear that you can install. Note that an update's size may vary from computer to computer when installed using Software Update. Also, some updates must be installed prior to others, so you should run Software Update more than once to make sure you have all available updates.



Standalone installer

Download the update installer and run it manually. This a useful option when you need to update multiple computers but only want to download the update once. These versions of the standalone installer are available from Apple Support Downloads:

• The delta update for PowerPC updates Mac OS X Server 10.4.10 (PowerPC) to 10.4.11.
• The delta update for Intel-based or PowerPC-based Macs updates Mac OS X Server 10.4.10 (Universal) to 10.4.11.
• The combo update installer for PowerPC updates Mac OS X Server (PowerPC) 10.4, 10.4.1, 10.4.2, 10.4.3, 10.4.4, 10.4.5, 10.4.6, 10.4.7, 10.4.8, 10.4.9 or 10.4.10 to 10.4.11.

• The combo update for Intel-based or PowerPC-based Macs (called the "Universal Update") updates any version of Mac OS X Server 10.4.x (Universal) to version 10.4.11 on PowerPC-based and Intel-based Macs.
