The MacBook Pro (sometimes abbreviated MBP〔(【引用サイトリンク】title=Apple MacBook Pro review: late-2013 model with Retina display & Nvidia graphics )〕) is a line of Macintosh portable computers introduced in January 2006 by Apple Inc., now in its third generation. Replacing the PowerBook G4, the MacBook Pro was the second model to be announced in the Apple–Intel transition, after the iMac. It is the high-end model of the MacBook family and is currently produced with 13- and 15-inch screens. A 17-inch version was available in the past. The first generation MacBook Pro appeared externally similar to the PowerBook G4, but used the Intel Core processors instead of PowerPC G4 chips. The 15-inch model was introduced first, in January 2006; the 17-inch model followed in April. Both received several updates and Core 2 Duo processors later that year. The computer's second generation, known as the "unibody" model, has a more tapered design and a casing made from a single block of aluminum. It debuted in October 2008 as the 15-inch MacBook Pro and the 13-inch aluminum unibody MacBook. The following January brought the design to the 17-inch model, along with the built-in battery that joined the rest of the MacBook Pro line in June, during which Apple also absorbed the unibody 13" Macbook into the MacBook Pro line. Subsequent updates brought upgraded Intel Core i5 and i7 processors and introduced Intel's Thunderbolt technology. Apple released the third generation of MacBook Pro in June 2012 with a 15-inch screen. At the same time, the 17-inch variant was discontinued, and slightly updated versions of the previous generation 13- and 15-inch unibody models were announced and sold in parallel. While dimensionally smaller than its predecessor, the similarly styled third generation model retained a unibody design. The most substantial differences in the third generation MacBook Pro are the fitting of a significantly higher resolution Retina display, the elimination of the optical drive, and replacement of hard disk drives with solid-state drives. A 13-inch third generation MacBook Pro was released in October 2012. ==1st generation== The original 15-inch MacBook Pro was announced on January 10, 2006 by Steve Jobs at the Macworld Conference & Expo. The 17-inch model was unveiled on April 24, 2006. The first design is largely a carryover from the PowerBook G4, but uses Intel Core CPUs instead of PowerPC G4 chips. The 15-inch MacBook Pro weighs the same as the 15-inch aluminum PowerBook G4, but is deeper, wider, and thinner. Other changes from the PowerBook include a built-in iSight webcam and the inclusion of MagSafe, a magnetic power connector designed to detach easily when pulled to prevent the entire laptop from being pulled off a surface. Both features were later brought over to the MacBook. In order to fit into the slimmer MacBook Pro, the optical drive is half the speed of the one in the PowerBook G4 and cannot write to dual layer DVDs.〔 Both the original 15- and 17-inch model MacBook Pros come with ExpressCard/34 slots, which replace the PC Card slots found in the PowerBook G4. All pre-unibody 15-inch models have two USB 2.0 ports and one FireWire 400 port,〔 while the 17-inch models have three USB 2.0 ports as well as one FireWire 400 port.〔 When first introduced, the MacBook Pro did not come with FireWire 800 or S-Video ports,〔〔 although FireWire 800 was added in the next 15-inch model revision and is present in every version of the 17-inch design.〔 S-Video capability can be attained through the use of a DVI to S-Video adapter.〔 External displays with up to a 2,560 × 1,600 pixel resolution are supported through a dual-link DVI port.〔 All models include a built-in Gigabit Ethernet port, Bluetooth 2.0, and 802.11a/b/g.〔〔 Later models include support for the draft 2.0 specification of 802.11n〔 and Bluetooth 2.1. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MacBook Pro」の詳細全文を読む スポンサード リンク
