The MacBook

The MacBook is a brand of Macintosh laptops designed and marketed by Apple Inc. that have been running Apple's macOS operating system since 2006. It replaced the PowerBook and iBook brands during the Mac's transition to Intel processors, announced in 2005. The current line consists of the MacBook Air (2008-present) and the MacBook Pro (2006-present). Two different lines simply called "MacBooks" existed from 2006 to 2012 and from 2015 to 2019.

On 10 November 2020, Apple announced MacBook Air and MacBook Pro models incorporating Apple's new M1 system on a chip.

The MacBook family was initially housed in a design similar to the iBook and PowerBook lines that preceded them, now making use of an aluminium unibody construction first introduced with the MacBook Air. This new construction also features a black plastic keyboard that was first used on the MacBook Air, which in turn was inspired by the sunken keyboard of the original polycarbonate MacBooks. The now-standardised keyboard brings congruence to the MacBook line, with black keys on an aluminium metal body.

The lids of the MacBook family are held closed by a magnet without a mechanical latch, a design element first introduced with the polycarbonate MacBook. Memory, drives, and batteries were accessible in the older line of MacBooks, although the newer compact line welds or glues all these components in place. All current MacBooks have backlit keyboards.

The MacBook was discontinued from February 2012 to March 2015, when a new model with an ultraportable design and an all-metal enclosure was introduced. It was discontinued again in July 2019 following a price reduction of the third-generation MacBook Air and the discontinuation of the second-generation model.
