With a Retina display and a thin, lightweight design, the gold mid 2017 Apple 12" MacBook provides both portability and performance. Measuring just 0.5" (13.1mm) thin and weighing only 2 pounds, the MacBook is compact yet still has a premium feel, thanks to its unibody design. The MacBook features a 12" Retina display with 16:10 aspect ratio and 2304 x 1440 native resolution, which results in 226 pixels per inch (ppi). The display also has 178?-wide viewing angles. To deliver the total Retina experience on the MacBook, Apple redesigned the pixels to create a larger aperture, allowing more light to pass through. This enabled Apple to use LED backlighting that's 30 percent more energy efficient than the displays on other Mac notebooks with no loss in brightness.
