MacBook Pro

A MacBook Pro is a type of laptop computer made by "Apple Inc." It replaced the PowerBook G4 and was the second Intel model to be released. It runs macOS and comes with a built in webcam and microphone and a power adapter that is attached by magnets. MacBook Pros are housed in aluminum metal and are currently available in 13", 14" and 16" models.
History.
The MacBook Pro was first introduced on January 2006 at the Macworld Expo. In June 2020, at the WWDC, Apple announced that Macs will be transitioning from Intel processsors to Apple silicon.
Models.
The first MacBook Pro was the 15" model, but a 17" model was released later that year. New models were released in late 2006, late 2007, early 2008, late 2008, and early 2009. In June 2009, a 13" model was added and the other sizes were also updated. The next updates happened in April 2010 and February 2011. Another update was released in June 2012, in which a new 15" model was introduced with a much higher display resolution (dubbed the Retina Display, meaning that it can display more pixels, creating a smoother image). However, Apple stopped making the 17" model.
In September 2016, Apple released the MacBook Pro with Touch Bar, a strip that replaces function keys. It came in 13" and 15" models. Updates followed in mid 2017, mid 2018 and mid 2019. The 16-inch MacBook Pro, featuring Intel Core i7 or i9 processors, was released in November 2019. It replaced 15-inch MacBook Pro. In early 2020, 13-inch model had been updated with new 10th gen Intel Core and Intel Iris Plus graphics.
In November 2020, Apple made a move from Intel processors to Apple Silicon with 13-inch MacBook Pro. It features an 8-core CPU, 8-core graphics and 16-core Neural Engine. The battery life has been extended to 20 hours. However, Apple continued selling Intel-based MacBook Pro until October 2021, when the new 14- and 16-inch MacBook Pro with either M1 Pro or M1 Max processor has been released.
Features.
The new MacBook Pro has several features:

Battery.
A built-in battery gives around 10 to 11 hours of power to Intel-based models and around 17 to 21 hours of power to Apple silicon models of the computer. This battery can be recharged up to 1,000 times, whereas typical notebooks can only be recharged 200 to 300 times.
