The MacBook is a brand of notebook computers manufactured by Apple Inc. from early 2006 to late 2011.
It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple-Intel transition from PowerPC.
A third design, introduced in January 2009, reverted to the polycarbonate shell and, in response to customer backlash, reverted to Firewire again like all MacBooks prior to the Late 2008 model. In this sense, it was really the first design revisited. A Mid 2009 model also had Firewire, but with the Late 2009 release, Firewire was again dropped by Apple.
On July 20, 2011, the MacBook was quietly discontinued for consumer purchase as it had been effectively superseded by the MacBook Air whose starting price was lowered. Apple continued to sell the MacBook to educational institutions until February 2012.
