Mac book

The MacBook is a brand of Macintosh notebook computers by Apple Inc. First introduced in May 2006 it replaced the iBook and 12-inch PowerBook series of notebooks as a part of the Apple Intel transition. Part of the MacBook family, the MacBook is aimed at the consumer and education markets.[1] It is the best-selling Macintosh in history, and according to the sales-research organization NPD Group in October 2008, the mid-range model of the MacBook was the single best-selling laptop of any brand in U.S. retail stores for the preceding five months.
The design had stylistic traits of the MacBook Air which were also implemented into the design of the MacBook Pro. This

model was thinner than the original polycarbonate MacBooks, and it made use of a unibody aluminum case with tapered edges. The keyboard of only the higher-end model was offered with a backlight.

MacBook is easier for users to fix or upgrade than its predecessor. Where the iBook required substantial disassembly to access most internal components, including removal of the keyboard and RAM, users need only remove the polycarbonate MacBook's outer shell to access almost any interior component. Replacing the hard drive and memory requires merely the removal of the battery, and Apple provides do-it-yourself manuals for these tasks.
