The MacBook Air is a line of laptop computers developed and manufactured by Apple since 2008. It features a thin, light structure in a machined aluminum case and a 13-inch (updated in 2022) and a 15-inch screen (2023). The Macbook Air's lower prices relative to the larger, higher performance MacBook Pro have made it Apple's entry-level notebook since the discontinuation of the original MacBook line in 2011.
The MacBook Air was introduced in January 2008 as a premium ultraportable with a 13.3-inch screen and a full-size keyboard, and was promoted as the world's thinnest notebook, opening a laptop category known as the ultrabook family. With its slim design, it attracted attention for not including an optical disc drive, and having fewer ports than was typical for laptops at the time.
In 2010 the MacBook Air was redesigned with a tapered chassis, and Apple released a smaller 11.6-inch version.
