MacBook Pro

The MacBook Pro is a line of high-end laptop computers made by Apple Inc. It replaced the PowerBook G4 and was the second model, after the iMac, to be announced in the Apple–Intel transition. The MacBook Pro is the high end laptop of the MacBook family and is currently produced with 13-inch, 14-inch and 16-inch sized screens.

1st generation
There have been several major designs for the MacBook Pro, all using aluminum. The first was largely a carry-over from the PowerBook G4, but used the Intel Core processors instead of PowerPC G4 chips. A 15-inch model was released in January 2006, followed by a 17-inch model in April 2006, both of which received several updates and Core 2 Duo processors later in the year.

2nd generation
The second unibody model has a more tapered design and a casing made from a single block of aluminum. It debuted in October 2008 as the 15-inch MacBook Pro and the 13-inch aluminum unibody MacBook. The following January brought the design to the 17-inch model, along with the built-in battery that joined the rest of the MacBook Pro line in June. Subsequent updates brought upgraded Intel Core i5 and Intel Core i7 processors and introduced Intel's Thunderbolt technology.

3rd generation
At WWDC 2012, a new line of MacBook Pros were introduced with Retina displays. Thunderbolt replaced the previous FireWire ports and power was supplied by a new MagSafe 2 connector.

4th generation
In 2016, the Touch Bar and Apple T1 security chip were introduced. In November 2019, a new 16-inch size replaced the 15-inch version and incorporated the improved Magic Keyboard.

In May 2020, the 13-inch model also incorporated the Magic Keyboard. In November 2020, the 13-inch model was updated to incorporate the Apple M1 chip. On June 6, 2022, a revised 13-inch model with the Apple M2 chip was introduced. Other than the processor, the design remained mostly unchanged. It became available for pre-order on June 17 with initial units becoming available on June 24. However, supply chain issues have caused some custom configurations to become back-ordered as far as August 2022.

5th generation
In October 2021, new 14-inch and 16-inch models were introduced. It included several improvements over the previous generation, including the return of function row keys, the return of HDMI and SDXC ports, and a larger, miniLED display. Featuring up to 8TB of storage, and faster Apple M1 Pro and M1 Max chips. The models were updated in January 2023, with Apple M2 Pro and M2 Max chips.
