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 Apple unveiled fourth generation 13- and 15-inch MacBook Pro models during a press event at their headquarters on October 27, 2016. The models introduced the Touch Bar, a multi-touch enabled OLED strip built into the top of the keyboard in place of the function keys. They include a sapphire-glass covered Touch ID sensor at the right end of the Touch Bar which doubles as a power button. The models also introduce a "second-generation" butterfly mechanism keyboard that provided more travel than the first iteration implemented on the Retina MacBook. The 13-inch model has a trackpad that is 46% larger than its predecessor while the 15-inch model has a trackpad twice as large as the prior generation.
