Important: Read below before installing.
- It is recommended that you back up your system prior to installing any updates.

- 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.
Installing the update
To update to Mac OS X 10.5.4, use Software Update or the standalone installer. You only need to use one of these methods to update your computer.
Choose Software Update from the Apple menu to automatically check for the latest Apple software using the Internet, including this update. (Software Update might have linked you to this article to learn more about the update.) If your computer is not up-to-date, other software updates available for your computer may appear which you should 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.
Download the update installer and run it manually. This is a useful option when you need to update multiple computers but only want to download the update once. These versions of the standalone installers are available from Apple Support Downloads.
The Mac OS X 10.5.4 Update is recommended for all versions of Mac OS X 10.5 through 10.5.3.
- The delta update lets you update from Mac OS X 10.5.3 to 10.5.4
- The combo update lets you update from Mac OS X 10.5, 10.5.1, 10.5.2, or 10.5.3 to 10.5.4
