AIRBOOK 13 INCH PRO
In October of 2021, Apple introduced the fifth-generation MacBook Pro with not one but two updated versions of the M1 chip, the M1 Pro and M1 Max. The ARM-based processor brought down power consumption and increased performance. In late-2020, Apple introduced the M1 chip and updated the 13-inch MacBook Pro. In place of function keys, the MacBook Pro gained an OLED Touch Bar. Instead, this redesigned MacBook Pro opted for all Thunderbolt 3 ports and headphone jack. No more MagSafe, no more USB-A ports, and only the 13-inch model kept the function keys. While the third generation received some backlash for the removal of ethernet and the optical drive, the fourth generation was a complete rethinking of the device peripherals.

Perhaps the most controversial version of the MacBook Pro is the fourth generation. The third-generation MacBook Pro introduced the retina display as well as MagSafe 2. The second generation of the MacBook Pro was the first to really separate itself from the products before, with a unibody enclosure. The first generation MacBook Pro followed in the style of the PowerBook G4 that came before it, but used Intel processors rather than PowerPC chips.

AIRBOOK 13 INCH UPGRADE
Previously, Apple had only offered the Pro model in 15 and 17 inch varieties starting in 2006, but decided to upgrade and rebrand the white, polycarbonate 13 inch MacBook to offer a smaller model in the Pro lineup. Apple's first 13" MacBook Pro was an aluminum unibody laptop released in mid 2009.
