when did the first macbook pro retina come out
MacBook Pro On June 11, 2012 at the Apple Worldwide Developers Conference in San Francisco, Apple introduced the third generation MacBook Pro, marketed as the "MacBook Pro with Retina display" to differentiate it from the predecessor model.[51] The new model includes Intel's third generation Core i7 processors (Ivy Bridge microarchitecture), USB 3.0, and a high-resolution 15.4" IPS 2880Ã—1800-pixel Retina Display.[52] Other new or changed features include a second Thunderbolt port, a HDMI port, and a thinner MagSafe port, dubbed the "MagSafe 2".[97] Apple introduced a 13-inch version on October 23, 2012 with specifications similar but slightly inferior to the 15-inch version's, such as less powerful processors.[98]
MacBook Pro At Apple's Worldwide Developers Conference (WWDC) on June 8, 2009, it was announced that the 13-inch unibody MacBook would be upgraded and re-branded as a MacBook Pro,[40] leaving only the white polycarbonate MacBook in the MacBook line.[41] It was also announced that the entire MacBook Pro line would use the non user-removable battery first introduced in the 17-inch MacBook Pro.[42] The updated MacBook Pro 13- and the 15-inch would each have up to a claimed seven hours of battery life, while the 17-inch would keep its eight-hour capacity.[40][42] Some sources even reported up to eight hours of battery life for the 13- and 15-inch MacBook Pros during casual use,[43] while others reported around six hours.[35] Like the 17-inch MacBook Pro, Apple claims that they will last around 1,000 charge cycles while still containing 80 percent of their capacity.[44] Graphics card options stayed the same from the previous release, although the 13-inch[45] and the base model 15-inch, came with only the GeForce 9400M GPU.[46] The screens were also improved, gaining a claimed 60 percent greater color gamut.[45][46] All of these mid 2009 models also included a FireWire 800 port and all except the 17-inch models would receive an SD card slot.[32] The 17-inch model would retain its ExpressCard/34 slot.[42] For the 13-inch MacBook Pro, the Kensington lock slot was moved to the right side of the chassis.[47] In August 2009, Apple extended the "matte" anti-glare display option to the 15-inch MacBook Pro.[48]
MacBook Pro The fourth generation MacBook Pro was announced on October 27, 2016. It replaces the function keys with an interactive, multi-touch "Touch Bar" and a Touch ID sensor integrated into the Power button.

MacBook Pro Apple released the third generation of MacBook Pro with a 15-inch screen during WWDC 2012 and discontinued the 17-inch variant. The previous generation 13- and 15-inch unibody models continued to sell with updated processors. The third generation model was a quarter thinner than its predecessor and introduced the Retina Display with a much higher screen resolution. A 13-inch variant was released in October 2012.
