when did the macbook pro 15 inch come out
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]
MacBook (12-inch) The MacBook is a line of Macintosh portable computers introduced in March 2015 by Apple Inc.[1] The MacBook has a similar appearance to the MacBook Air, but is thinner and lighter,[2] and is available in colors called space gray, silver, gold, and rose gold. It offers a high-resolution Retina Display, a Force Touch trackpad, a redesigned keyboard, and only two ports: a headphone jack and a USB 3.1 Type-C port for charging, data transfer and video output.
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]
