About the Mac OS X Server v10.6.7 Update

This software updates Mac OS X Server v10.6, v10.6.1, v10.6.2, v10.6.3, v10.6.4, v10.6.5, or v10.6.6 to v10.6.7.

This article has been archived and is no longer updated by Apple.

Important: Read before installing.

  • Do not interrupt the installation process. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Support Downloads to update.
  • The Mac OS X Server v10.6.7 Combo Update overwrites the /etc/rc.server file. If you have previously made changes to this file, make a backup copy before updating. Any custom sysctl settings should be configured in /etc/sysctl.conf rather than /etc/rc.server. See man rc.server and the /etc/sysctl.conf.default file for details.
  • 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.)
  • 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 v10.6.7. The simplest way to avoid issues from an improper installation is to start up from the volume that you wish to update.


There are three ways to update to Mac OS X Server v10.6.7:

  • Use Software Update
  • Install from a standalone installer
  • Install on a remote server via Server Admin or the softwareupdate command-line utility

Software Update installation

Software Update may have referred you to this article. Because some updates are prerequisites for others, you may need to use Software Update more than once to obtain all available updates.

Standalone installer

If you want to download and manually install the update, an installer is available from Apple Support Downloads. This a useful option if you need to update multiple computers but only want to download the update once.

Remote installation

If you need to install the update on a remote server, you can do so using the Server Admin application or the softwareupdate command-line tool.
