The MacBook Pro is a line of Macintosh portable computers introduced in January 2006, by Apple Inc. It is the higher-end model of the MacBook family, sitting above the consumer range MacBook Air, and is available in 13- and 15-inch screen sizes.
The first-generation MacBook Pro is externally similar to the PowerBook G4 it replaced, but uses Intel Core processors instead of PowerPC G4 chips.
The product’s second iteration, known as the “unibody” model, has a casing made from a single piece of aluminum.
