Mac OS X Update 10.1.5: Enhancements and "Before You Install" Information

This software updates Mac OS X (version 10.1, 10.1.1, 10.1.2, 10.1.3, or 10.1.4) to version 10.1.5.

Important: Read Before Installing

1. An Admin user password that does not contain spaces or Option-keyed characters is required to install. The password may not be blank. If your password must be changed, then follow these steps: Choose System Preferences from the Apple menu. Choose Users from the View menu. Select and Admin user and click Edit User. Click the Password tab. Change the password and click OK.

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

3. The installation process should not be interrupted. Monitor progress by clicking the Detailed Progress disclosure triangle. If you experience a power outage or other interruption during installation, use the standalone installer (see below) from Apple Software Downloads to install.

4. Prerequisite software must be present before you can install Mac OS X Update 10.1.5, whether you are using Automatic Software Update or standalone installers. Updates must be installed in the correct order. For the correct sequence, see technical document 106713, "Mac OS X 10.1: Chart of Available Software Updates".

Installation

There are two ways to update to Mac OS X 10.1.5.

I. Automatic Software Update Installation

See technical document 106704, "Mac OS X: How to Update Your Software".

Because some updates are prerequisites for others, you may need to use Software Update more than once to get all desired updates.


II. Standalone Installer

Standalone installers are available from Apple Software Downloads (http://www.apple.com/swupdates/). Two versions are available. See technical document 106713, "Mac OS X 10.1: Chart of Available Software Updates".

You should not reinstall certain earlier updates after using this update, including:

• Mac OS X 10.0.1
• Mac OS X 10.0.2
• Mac OS X 10.0.3
• Mac OS X 10.0.4
• Mac OS X 10.1
