what are the different sizes of macbook pro
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]
MacBook Pro The original 15-inch MacBook Pro was announced on January 10, 2006 by Steve Jobs at the Macworld Conference & Expo.[4] The 17-inch model was unveiled on April 24, 2006.[5] The first design was largely a carryover from the PowerBook G4, but uses Intel Core CPUs instead of PowerPC G4 chips.[6] 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.[7] 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 cannot write to dual layer DVDs.[6][8]
MacBook Pro The macOS operating system has been pre-installed on all MacBook Pros since release, starting with version 10.4.4 (Tiger).[4] Along with OS X, iLife has also shipped with all systems, beginning with iLife '06.[4]
iPad In June 2017, the iPad Pro's second generation hardware was announced to have 12.9 and 10.5-inch screens.[67]
