The 12-inch MacBook (also called the Retina MacBook, officially marketed as the new MacBook) is a discontinued Mac laptop made by Apple, which sat between the MacBook Air and MacBook Pro in Apple's laptop lineup. It shares the same name as its predecessor that was discontinued three years prior to its release.
Introduced in March 2015, it was more compact than any other notebook in the MacBook family at the time and included a Retina display, fanless design, and a Butterfly keyboard with lower key travel. It only had a single USB-C port, used for both power and data. It was revised in 2017, and discontinued in July 2019.
