There have been three separate designs of the original MacBook. For five months in 2008, it was the best-selling laptop of any brand in US retail stores. It became the best-selling Mac in Apple's history.

Positioned as the low end of the MacBook family, below the premium ultra-portable MacBook Air and the performance-oriented MacBook Pro, the MacBook was aimed at the consumer and education markets. It replaced the iBook series of notebooks as a part of Apple's transition from PowerPC to Intel processors. The MacBook is a line of Mac laptops sold by Apple Inc.
