Processor
When you install the Xcode tools, the Processor preference pane will be placed in the /Developer/
Extras/PreferencePanes/ folder. Should you install this into one of the PreferencePanes folders in
one of your libraries, it will be available to you. The Processor preference pane (Figure 4-31) provides
information about your computer’s processors, and allows you to tweak some options (like
disabling processor cores, toggling napping (PPC chips), and other things that are of little to no
use for most people). In general, it’s best to leave this alone unless you know what you are doing.
While altering anything here won’t destroy anything, your computer processing power could suffer.

Sound
CHAPTER 4 SYSTEM PREFERENCES 77
The Sound preference pane controls your sound input and output devices, and provides options
for system sounds and effects. The Sound preference pane has three tabs: Sound Effects, Output,
and Input.
The Sound Effects tab (Figure 4-32) allows you to set your alert sound (the sound your computer
plays when it tries to get your attention—usually when something bad happens).
Figure 4-32. The Sound Effects tab lets you choose your system alert sound and provides a few options
for audio feedback.
