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 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.
MacBook Pro The fourth generation MacBook Pro was announced on October 27, 2016. It replaces 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 June 5, 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]

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.
