MacBook

The MacBook is a brand of notebook computers manufactured by Apple Inc.. from early 2006 to late 2011, and relaunched in 2015. It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of the Apple-Intel transition from PowerPC. Positioned as the low end of the MacBook family, below the premium ultra-portable MacBook Air and the powerful MacBook Pro, the MacBook was aimed at the consumer and education markets. It was the best-selling Macintosh ever. For five months in 2008, it was the best-selling laptop of any brand in US retail stores. Collectively, the MacBook brand is the "world's top-selling line of premium laptops."
There have been four separate designs of the MacBook. The original model used a combination of polycarbonate and fiberglass casing which was modeled after the iBook G4. The second type was introduced in October 2008 alongside the 15-inch MacBook Pro; the MacBook shared the more expensive laptop's unibody aluminum casing, but omitted FireWire, which hurt sales. A third design, introduced in late 2009, had a polycarbonate unibody casing and no FireWire ports.
On July 20, 2011, the MacBook was quietly discontinued for consumer purchase as it had been effectively superseded by the MacBook Air whose starting price was lowered.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.
A new, redesigned MacBook line was launched on March 9, 2015. Available in silver, gold or space grey, it is thinner than the MacBook Air and removes the traditional MagSafe charging port (along with all other ports, except the headphone jack) in favor of the multi-purpose USB Type-C port.
==Original polycarbonate model ==

The original MacBook, available in black or white colors, was released on May 16, 2006, and used the Intel Core Duo processor and 945GM chipset, with Intel's GMA 950 integrated graphics on a 667 MHz front side bus. Later revisions of the MacBook moved to the Core 2 Duo processor and the GM965 chipset, with Intel's GMA X3100 integrated graphics on an 800 MHz system bus.〔(【引用サイトリンク】title=White & Black MacBook Q&A – Revised March 1, 2008 )〕 Sales of the black polycarbonate MacBook ceased in October 2008, after the introduction of the aluminum MacBook.

While thinner than its predecessor – the iBook G4 – the MacBook is wider than the 12-inch model due to its widescreen display. In addition, the MacBook was one of the first (the first being the MacBook Pro) to adopt Apple's MagSafe power connector and it replaced the iBook's mini-VGA display port with a mini-DVI display port. The iBook's discrete graphics chip was initially replaced by an integrated Intel GMA solution, though the latest revisions of the MacBook were upgraded with the more powerful Nvidia GeForce 9400M and later the 320M.
While the MacBook Pro largely followed the industrial design standard set by the PowerBook G4, the MacBook was Apple's first notebook to use features now standard in its notebooks – the glossy display, the sunken keyboard design and the non-mechanical magnetic latch. With the late 2007 revision, the keyboard received several changes to closely mirror the one which shipped with the iMac, by adding the same keyboard short-cut to control multimedia, and removing the embedded numeric keypad and the Apple logo from the command keys.
A more expensive black model was offered until the introduction of the unibody aluminum MacBook. The polycarbonate MacBook was the only Macintosh notebook (until the new 2015 model) to be offered in more than one color since the iBook G3 (Clamshell).
