The Retina MacBook Pro was released in 2012: the 15-inch in June, a 13-inch model in October. Updates brought Intel Core i5 and i7 processors and introduced Intel's Thunderbolt. Called 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 consisted of a single clickable button, and a redesigned keyboard. The unibody model debuted in October 2008 in 13- and 15-inch variants, with a 17-inch variant added in January 2009. Later revisions added Intel Core 2 Duo processors and LED-backlit displays.

The 15-inch model was introduced in January 2006 the 17-inch model in April. The original 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.

It is currently sold with 13-inch, 14-inch, and 16-inch screens, all using Apple silicon M-series chips. Introduced in January 2006, it is the higher-end lineup in the MacBook family, sitting above the consumer-focused MacBook Air.
