This software updates Mac OS X Server 10.4.7 (Universal) to version 10.4.8. Note: If you have PowerPC-based Macintosh Servers with Mac OS X Server 10.4.7 (non-Universal) installed, you should use the Mac OS X Server (PowerPC) 10.4.8 Update instead.
Important: Please Read Before Installing
- After installing this update, the computer will restart two times—the first restart after installing this update may take several minutes; please allow it to complete.
- You must have an administrator account password that does not contain Option-keyed characters to install this update. The password may not be left blank (you can change your password if needed).
- You may experience unexpected results if you've installed third-party system software modifications, or if you have modified the operating system through other means. This doesn't apply to normal software installation.
- The installation process should not be interrupted. Monitor progress by clicking the Detailed Progress disclosure triangle. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to install.
- This update can be installed on non-startup volumes, but you should only do this if the current startup volume has already been updated to Mac OS X Server 10.4.8. The simplest way to avoid issues from an improper installation is to start up from the volume that you wish to update.
