How to Update Mac OS X
1. Choose About This Mac from the Apple Menu to determine which version of Mac OS X you have installed.
Note: If your version is 10.0.4 or earlier, you must update to Mac OS X 10.1 before you can install the latest software. This requires a 10.1 update CD.
Once you know which version you have installed, you may update one of two ways, Automatic Software Update or by using standalone installers from Apple Software Downloads (
http://www.apple.com/swupdates/).
Automatic Software Update
Automatic Software Update is available in the System Preferences application. For more information on how to use it, see technical document 106704: "
Mac OS X: How to Update Your Software".
Manual update using standalone installer
You can download software updates from Apple Software Downloads (
http://www.apple.com/swupdates/). Some updates must be installed in a specific sequence, which is described in technical document 106713: "
Mac OS X 10.1: Chart of Available Software Updates".
