Chapter 3 Using Your MacBook 69
For applications that can record sounds, such as iMovie HD, use the Sound pane of
System Preferences to select the audio input device you want to use, including
microphones connected through USB.
The volume controls on your keyboard allow you to easily adjust the output volume.
You can also adjust both the input and output volume from the Sound pane of System
Preferences.
For more information about using or troubleshooting sound on your computer, choose
Help > Mac Help and search for “sound.”
Using Your Optical Drive
Your MacBook includes an optical drive—either a Combo drive or a SuperDrive.
With your optical drive, you can:
 Install or use software from CDs and DVDs.
 Play music and multimedia files from CDs.
 Write music, documents, and other digital files to CD-R and CD-RW discs.
 Play DVD movies and read most DVD discs.
If you have a SuperDrive, you can also record information on blank DVD±R and
DVD±RW discs.
Important: The optical drive on your MacBook supports standard circular 12 cm discs.
Irregularly shaped discs or discs smaller than 12 cm are not supported. These types of
discs can become lodged in the drive.
