Mac OS X 10.4: Optional Installs may install previous versions of certain applications
Symptoms
If you want to install items found in the Optional Installs package on the Mac OS X 10.4 Tiger discs, make sure that you only install from a disc with the same version of Mac OS X that's on your computer, such as Mac OS X 10.4 or 10.4.2. Otherwise, you may end up installing previous versions of certain applications, which can cause applications to become unresponsive.
Products Affected
Mac OS X 10.4, Mac OS X 10.3, Mac OS X 10.2
Resolution
If you've already done this and are experiencing issues with an application, try updating to the latest version of Mac OS X 10.4 via a Combo update from Apple Downloads, or updating to the latest version of the affected application.
Once you've updated, do not use Option Installs from the Tiger discs to reinstall those applications.
Additional Information
The Optional Installs package allows you to reinstall certain bundled applications included with Tiger. Specifically, these are: Address Book, iCal, iChat, iTunes, Mail, Oxford Dictionaries, Safari, and X11.
