Apple MacBook Pro
The Apple MacBook Pro is a line of Macintosh portable computers introduced in January 2006, by Apple Inc. It is the higher-end model of the Laptop Macbook family, sitting above the consumer-focused MacBook Air, and is available in 13-inch and 16-inch screen sizes. A 17-inch version was sold from April 2006 to June 2012.
The first-generation Laptop macbook Pro used the design of the PowerBook G4, but replaced the PowerPC G4 chips with Intel Core processors, added a webcam, and introduced the MagSafe power connector. The 15-inch model was introduced in January 2006; the 17-inch model in April. Later revisions added Core 2 Duo processors and LED-backlit displays.
The second-generation model debuted in October 2008 in 13- and 15-inch variants, with a 17-inch variant added in January 2009. Known as the "unibody" model because its case was machined from a single piece of aluminum, it had a thinner flush display, a redesigned trackpad whose entire surface was a single clickable button, and a redesigned keyboard. Updates brought Intel Core i5 and i7 processors and introduced Intel's Thunderbolt technology.
The third-generation MacBook Pro was released in 2012: the 15-inch in June 2012, a 13-inch model in October. It is thinner than its predecessor, makes solid-state storage (SSD) standard, and includes a high-resolution Retina display.
The fourth-generation NoteBook was released in October 2016. This generation uses USB-C for all data ports and power. It includes a shallower "butterfly"-mechanism keyboard. On all but the base model, the function keys were replaced with a touchscreen strip called the Touch Bar with a Touch ID sensor integrated into the power button.
The fifth-generation NoteBook returned to a scissor-mechanism keyboard. A 16-inch model with a screen set in narrower bezels was released in November 2019, and a 13-inch model was released in May 2020.
