MacBook - online puzzles

The MacBook is a brand of notebook computers manufactured by Apple Inc. from May 2006 to February 2012, and relaunched in 2015. It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple - Intel transition from PowerPC. Positioned as the low end of the MacBook family, below the premium ultra-portable MacBook Air and the powerful MacBook Pro, the MacBook was aimed at the consumer and education markets. It was the best- selling Macintosh ever. For five months in 2008, it was the best- selling laptop of any brand in US retail stores. Collectively, the MacBook brand is the " world 's top- selling line of premium laptops."

There have been four separate designs of the MacBook. The original model used a combination of polycarbonate and fiberglass casing which was modeled after the iBook G4. The second type was introduced in October 2008 alongside the 15-inch MacBook Pro ; the MacBook shared the more expensive laptop 's unibody aluminium casing, but omitted FireWire. A third design, introduced in late 2009, had a polycarbonate unibody casing.

On July 20, 2011, the MacBook was discontinued for consumer purchase as it had been effectively superseded by the MacBook Air whose starting price was lowered.
