Apple MacBook

Apple MacBook, a line of Macintosh notebook computers by Apple Inc. Introduced in May 2006, it replaced the iBook G4 and 12" PowerBook series of notebooks as a part of the Apple Intel transition. Part of the MacBook family, the MacBook is aimed at the education and consumer markets. It is the best-selling Macintosh in history, and according to the sales-research organization NPD Group, the midrange model of the MacBook has been the single best-selling laptop of any brand in U.S. retail stores for the past five months.

There have been two designs of the MacBook: the first uses a polycarbonate casing that was modeled after the iBook G4, while the second uses a unibody aluminum casing. When the aluminum MacBook was announced, the original white MacBook was given an optical drive update and a lower price. The aluminum MacBook was released in October 2008.
