The 12-inch MacBook was aimed at users who prioritized portability and minimalism, and it represented a significant step forward in Apple's laptop design.

In May 2015, Apple introduced the 15-inch MacBook Pro with a Retina display that included the new Force Touch trackpad. This trackpad technology allowed for pressure-sensitive inputs, offering new ways for users to interact with their MacBook Pro. The Force Touch trackpad was later incorporated into other MacBook models, reflecting Apple's commitment to enhancing user interaction through innovative hardware design.

In October 2016, Apple introduced the MacBook Pro with a Touch Bar, a multi-touch enabled OLED strip above the keyboard that replaced the function keys. This feature offered users customizable controls depending on the application in use, such as volume and brightness sliders, interactive ways to adjust or browse through content, and more. The Touch Bar was a bold attempt by Apple to innovate beyond traditional laptop interfaces, aiming to offer a more adaptive and intuitive user experience.

In October 2018, Apple updated the MacBook Air to include USB-C and Thunderbolt 3 ports. This update significantly enhanced the MacBook Air's connectivity options, allowing for faster data transfer, better external display support, and quicker charging.

In October 2018, alongside the USB-C and Thunderbolt 3 update, Apple introduced a Retina display to the MacBook Air. This was a significant upgrade from the previous models' standard displays, offering a much higher resolution that greatly enhanced visual clarity and detail. The addition of the Retina display to the MacBook Air marked a commitment to bringing high-end display technology to all of Apple's notebook lines.

In July 2019, Apple officially discontinued the 12-inch MacBook model, shifting its focus entirely to the MacBook Air and MacBook Pro lines. This decision was influenced by the overlapping features and price points between the MacBook and the newer MacBook Air, which offered better performance and value. The discontinuation allowed Apple to streamline its product offerings and focus on enhancing the features and capabilities of the remaining MacBook models.

In November 2019, Apple introduced the 16-inch MacBook Pro, the largest MacBook Pro since the discontinuation of the 17-inch model. This new model featured a larger screen, improved speakers, and a redesigned keyboard that replaced the controversial butterfly mechanism with a more reliable scissor mechanism.
