Package - Power Manager System Preference

The system preference provides a graphical interface for scheduling events.

The Power Manager System Preference package is recommended but not required.

Requirements

Mac OS X 10.4 or later is required for this package.

Files Installed

• /Library/PreferencePanes/Power Manager.prefPane

Files Created During Installation

The post installation script installs additional non-essential files.

/Library/PreferencePanes/Power Manager.prefPane

The adminAssistant provides a limited set of root level tasks for the System Preference. These tasks include launching the daemon and toggling the security rights for non-administrator users.

If adminAssistant is not installed, or is removed, the System Preference will replace it within the active user’s Library; an administrator password will be requested before adminAssistant is replaced.

Power Manager’s System Preference can be installed within a user’s Library/PreferencePanes to limit the interface to a single user.

Scripts

Preparation

This package does not use a preparation script.

Post Installation

The post installation script performs four tasks:

• Creates an Application Support folder for Power Manager;
• Copies the adminAssistant tool into the folder;
• Set the adminAssistant tool as sticky and user root:wheel;
• Creates a soft link to the Power Manager Help Book.

The Help Book link is created to overcome a limitation in the System Preferences. The Help Book should appear automatically and instantly when included in an installed Preference Pane; this is not the case.
