MacBook Pro At Apple's Worldwide Developers Conference (WWDC) on June 8, 2009, it was announced that the 13-inch unibody MacBook would be upgraded and re-branded as a MacBook Pro,[40] leaving only the white polycarbonate MacBook in the MacBook line.[41] It was also announced that the entire MacBook Pro line would use the non user-removable battery first introduced in the 17-inch MacBook Pro.[42] The updated MacBook Pro 13- and the 15-inch would each have up to a claimed seven hours of battery life, while the 17-inch would keep its eight-hour capacity.[40][42] Some sources even reported up to eight hours of battery life for the 13- and 15-inch MacBook Pros during casual use,[43] while others reported around six hours.[35] Like the 17-inch MacBook Pro, Apple claims that they will last around 1,000 charge cycles while still containing 80 percent of their capacity.[44] Graphics card options stayed the same from the previous release, although the 13-inch[45] and the base model 15-inch, came with only the GeForce 9400M GPU.[46] The screens were also improved, gaining a claimed 60 percent greater color gamut.[45][46] All of these mid 2009 models also included a FireWire 800 port and all except the 17-inch models would receive an SD card slot.[32] The 17-inch model would retain its ExpressCard/34 slot.[42] For the 13-inch MacBook Pro, the Kensington lock slot was moved to the right side of the chassis.[47] In August 2009, Apple extended the "matte" anti-glare display option to the 15-inch MacBook Pro.[48]
Macintosh 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 graphics workstation), and three laptops (the MacBook, MacBook Air, and the MacBook Pro). Its Xserve server was discontinued in 2011 in favor of the Mac Mini and Mac Pro.
MacBook Pro The fourth generation MacBook Pro was announced on October 27, 2016. It replaced the function keys with an interactive, multi-touch "Touch Bar" and a Touch ID sensor integrated into the Power button. The 15-inch notebook started at $2,399, compared to $1,999 for the previous iteration.[2] On 5 June 2017, Apple upgraded the internals of the MacBook Pro, such as enhanced Iris Plus and AMD Radeon graphics, Kaby Lake processors, and added memory. Additionally, the 13-inch MacBook Pro now comes with a 128GB storage option (down from the base 256GB storage) with a lowered starting price of $1299. All other configurations of the MacBook Pro have the same price as last year, barring the incremental upgrades in processors and graphics.[3]

MacBook Pro Apple unveiled fourth generation 13- and 15-inch MacBook Pro models during a press event at their headquarters on October 27, 2016. The models introduced the Touch Bar, a multi-touch enabled OLED strip built into the top of the keyboard in place of the function keys. They include a sapphire-glass covered Touch ID sensor at the right end of the Touch Bar which doubles as a power button. The models also introduce a "second-generation" butterfly mechanism keyboard that provided more travel than the first iteration implemented on the Retina MacBook. The 13-inch model has a trackpad that is 46% larger than its predecessor while the 15-inch model has a trackpad twice as large as the prior generation.
