paragraph_text: The MacBook was a line of Macintosh notebook computers designed, manufactured and sold by Apple Inc. from May 2006 to February 2012. A new line of computers by the same name was released in 2015, serving the same purpose as an entry-level laptop. It replaced the iBook series and 12-inch PowerBook series of notebooks as a part of Apple's transition from PowerPC to Intel processors. 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 aluminium casing, but omitted FireWire.  A third design, introduced in late 2009, had a polycarbonate unibody casing.

paragraph_text: In 1998, after the return of Steve Jobs, Apple consolidated its multiple consumer-level desktop models into the all-in-one iMac G3, which became a commercial success and revitalized the brand. Since their transition to Intel processors in 2006, the complete lineup is entirely based on said processors and associated systems. Its current lineup comprises three desktops (the all-in-one iMac, entry-level Mac mini, and the Mac Pro tower graphics workstation), and four laptops (the MacBook, MacBook Air, MacBook Pro, and MacBook Pro with Retina display). Its Xserve server was discontinued in 2011 in favor of the Mac Mini and Mac Pro.

paragraph_text: Starting with the release of the Apple Watch, Apple has begun usage of San Francisco as the typeface of word marks such as ``iPhone '',`` AirPods'', and ``MacBook Pro ''on the devices themselves. This change is also reflected on some headlines on product marketing webpages. Apple modified the majority of its website's text to use the San Francisco font on January 24, 2017, and San Francisco became the universal official font for Apple.

paragraph_text: On June 11, 2012 at the Apple Worldwide Developers Conference in San Francisco, Apple introduced the third generation MacBook Pro, marketed as the ``MacBook Pro with Retina display ''to differentiate it from the predecessor model. The new model includes Intel's third generation Core i7 processors (Ivy Bridge microarchitecture), USB 3.0, and a high - resolution 15.4'' IPS 2880 × 1800 - pixel Retina Display. Other new or changed features include a second Thunderbolt port, a HDMI port, and a thinner MagSafe port, dubbed the`` MagSafe 2 ''. Apple introduced a 13 - inch version on October 23, 2012 with specifications similar but slightly inferior to the 15 - inch version's, such as less powerful processors.

paragraph_text: The MacBook Pro (sometimes abbreviated as MBP) is a line of Macintosh portable computers introduced in January 2006 by Apple Inc. It is the high - end model of the MacBook family and is currently available in 13 - and 15 - inch screen sizes. A 17 - inch version was available between April 2006 and June 2012.

paragraph_text: By March 2011, the market share of OS X in North America had increased to slightly over 14%. Whether the size of the Mac's market share and installed base is relevant, and to whom, is a hotly debated issue. Industry pundits have often called attention to the Mac's relatively small market share to predict Apple's impending doom, particularly in the early and mid-1990s when the company's future seemed bleakest. Others argue that market share is the wrong way to judge the Mac's success. Apple has positioned the Mac as a higher-end personal computer, and so it may be misleading to compare it to a budget PC. Because the overall market for personal computers has grown rapidly, the Mac's increasing sales numbers are effectively swamped by the industry's expanding sales volume as a whole. Apple's small market share, then, gives the impression that fewer people are using Macs than did ten years ago, when exactly the opposite is true. Soaring sales of the iPhone and iPad mean that the portion of Apple's profits represented by the Macintosh has declined in 2010, dropping to 24% from 46% two years earlier. Others try to de-emphasize market share, citing that it is rarely brought up in other industries. Regardless of the Mac's market share, Apple has remained profitable since Steve Jobs' return and the company's subsequent reorganization. Notably, a report published in the first quarter of 2008 found that Apple had a 14% market share in the personal computer market in the US, including 66% of all computers over $1,000. Market research indicates that Apple draws its customer base from a higher-income demographic than the mainstream personal computer market.

paragraph_text: The sales breakdown of the Macintosh have seen sales of desktop Macs stayed mostly constant while being surpassed by that of Mac notebooks whose sales rate has grown considerably; seven out of ten Macs sold were laptops in 2009, a ratio projected to rise to three out of four by 2010. The change in sales of form factors is due to the desktop iMac moving from affordable (iMac G3) to upscale (iMac G4) and subsequent releases are considered premium all-in-ones. By contrast the MSRP of the MacBook laptop lines have dropped through successive generations such that the MacBook Air and MacBook Pro constitute the lowest price of entry to a Mac, with the exception of the even more inexpensive Mac Mini (the only sub-$1000 offering from Apple, albeit without a monitor and keyboard), not surprisingly the MacBooks are the top-selling form factors of the Macintosh platform today. The use of Intel microprocessors has helped Macs more directly compete with their Windows counterparts on price and performance, and by the 2010s Apple was receiving Intel's latest CPUs first before other PC manufacturers.

paragraph_text: The MacBook is an American line of notebook computers manufactured by Apple Inc. from May 2006 to February 2012, 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.

paragraph_text: 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 was 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 0.1 inches (0.25 cm) deeper, 0.4 inches (1.0 cm) wider, and 0.1 inches (0.25 cm) 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 yanked. These features were later brought over to the MacBook. The optical drive was reduced in size in order to fit into the slimmer MacBook Pro, hence it runs slower than the optical drive in the PowerBook G4 and can not write to dual layer DVDs.

paragraph_text: The MacBook Air is a line of Macintosh subnotebook computers developed and manufactured by Apple Inc. It consists of a full - size keyboard, a machined aluminum case, and a thin light structure.
