Apple Disc Burner makes it easy to create data CDs from your CD-RW drive. Burning CDs is easy: simply insert the blank disc and select the format you want to create. Then drag the contents onto the icon that appears on your desktop. Once you are done, select the disc and choose "Burn CD" in the Special menu.
This software currently supports only the new internal Apple CDRW drives. However, plug-ins for all models will soon be available.
