when did the 12 inch macbook come out
MacBook (12-inch) The MacBook is a line of Macintosh portable computers introduced in March 2015 by Apple Inc.[1] The MacBook has a similar appearance to the MacBook Air, but is thinner and lighter,[2] and is available in colors called space gray, silver, gold, and rose gold. It offers a high-resolution Retina Display, a Force Touch trackpad, a redesigned keyboard, and only two ports: a headphone jack and a USB 3.1 Type-C port for charging, data transfer and video output.
MacBook Pro The original 15-inch MacBook Pro was announced on January 10, 2006 by Steve Jobs at the Macworld Conference & Expo.[4] The 17-inch model was unveiled on April 24, 2006.[5] The first design was largely a carryover from the PowerBook G4, but uses Intel Core CPUs instead of PowerPC G4 chips.[6] The 15-inch MacBook Pro weighs the same as the 15-inch aluminum PowerBook G4, but is 0.1 inches (0.25 cm) deeper, 0.4 inches (1.0 cm) wider, and 0.1 inches (0.25 cm) thinner.[7] Other changes from the PowerBook include a built-in iSight webcam and the inclusion of MagSafe, a magnetic power connector designed to detach easily when yanked. These features were later brought over to the MacBook. The optical drive was reduced in size in order to fit into the slimmer MacBook Pro, hence it runs slower than the optical drive in the PowerBook G4 and cannot write to dual layer DVDs.[6][8]
