This article has been archived and is no longer updated by Apple.
Install these software updates for the best Mac OS X performance and feature set:
  • Software Update 1.3.1
  • 10.0.1 Update
  • Epson Printer Driver Update

Important: Before you install, read these notes.
    1. You must have an Admin user password to install this update. The password must not contain spaces and may not be blank. Certain characters may also produce unexpected results when used in a password. Generally, these characters are those you type with the Option key. To change your password, open System Preferences and click Users. Select an Admin user and click Edit User. Create a new password. For best security, put both numbers and letters within the first eight characters of the password.

    2. You may experience unexpected results if you have installed third-party modifications to system software or if you have modified the operating system through other means, such as the Terminal. This precautionary statement does not apply to the normal installation of application software.

    3. Do not interrupt the 10.0.1 Update installation process. You can monitor progress by clicking the Detailed Progress disclosure triangle. When viewing Detailed Progress, it is normal for the update to say "optimizing" for several minutes prior to completion. If you experience a power outage or other interruption during a software update installation, you should download the update from Apple Software Updates and reinstall it. "Optimizing" refers to the execution of a process called "update_prebinding," which allows applications to open faster by precalculating the address information of system data the applications use. This optimization is performed on the Mac OS X startup disk when Apple updates certain System components. Though update_prebinding may be executed manually, it is not necessary to use it at any other time.

Steps to install the updates

(You must first be connected to the Internet.)
    1. Quit open applications, which are marked in the Dock with a small triangle. You cannot quit the Finder.
    2. Choose System Preferences from the Apple menu.
    3. Click the Software Update icon.
    4. Click Update Now.

You may now install Software Update 1.3.1. You must install this update first to access the 10.0.1 Update, the Epson Printer Driver Update, and any future updates using the Software Update pane in System Preferences.

Repeat the steps above to install the 10.0.1 Update. Restart your computer after installing the 10.0.1 Update and repeat steps again to install the Epson Printer Driver Update.
