Chapter 15. System Preferences
The hub of Mac customization is System Preferences, the modern-day successor to the old Control Panel (Windows) or Control Panels (previous Mac systems). Some of its panels are extremely important, because their settings determine whether or not you can connect to a network or go online to exchange email. Others handle the more cosmetic aspects of customizing Mac OS X.
This chapter guides you through the entire System Preferences program, panel by panel.
Tip
