when did macbook pro touch bar come out
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]
Touchscreen A touchscreen is an input and output device normally layered on the top of an electronic visual display of an information processing system. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.[1] Some touchscreens use ordinary or specially coated gloves to work while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size.
