MacBooks come with enough software to let you play around with images, video, and music, as well as browse the Internet and communicate with friends online, right out of the box. Although your MacBook comes with an OS X installation DVD, you don't need to use it. You may use your MacBook straight away after purchasing it; the install CD is needed for troubleshooting and system restoration. Apple offers a number of apps that aren't included with the MacBook, including the iWork software package and Aperture.
