when was the latest macbook pro retina released
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.
MacBook Air Apple incorporated several features in the design of the MacBook Air, such as the reduction of lead to make it more environmentally friendly. The MacBook Air contains no BFRs and PVC wiring, meets Energy Star 5.0 requirements, has a recyclable enclosure, and is rated EPEAT Gold. Its display is made from arsenic-free glass, and contains no mercury.[7][32] To reduce the computer's size and weight, several features were sacrificed. It was Apple's first notebook since the PowerBook 2400c without a built-in removable media drive.[33] It also omits a FireWire port, Ethernet port, line-in, media card slots (except the 13" 2010 through 2015 models, which have an SD card slot), and a Kensington Security Slot.[34]
