The 12" Retina display on the MacBook doesn't just have a high resolution, but it's also paper thin. In fact, it is just 0.03" (0.88mm). A specially developed automated manufacturing process forms the edge-to-edge glass that's only 0.02" (0.5mm) thick. And Apple reduced the space between display components for a tighter, more integrated design. The Retina display has a 2304 x 1440 native resolution and a 16:10 aspect ratio. It also has 178° viewing angles, thanks to its IPS panel.
To deliver the Macbook's Retina experience, Apple redesigned the pixels to create a larger aperture, allowing more light to pass through. This enabled them to use LED backlighting that's 30 percent more energy efficient than the Retina display on previous models while still achieving the same level of brightness.
The Force Touch trackpad may look like other trackpads on the surface, but it's what is underneath that makes it distinct. Force sensors detect how much pressure you're applying, and the Taptic Engine provides a click sensation when you press anywhere on the surface. Now, the click that once was a single, mechanical function is just the start of what you can do with Force Touch. The sensory capabilities of the Force Touch trackpad allow you to tell your MacBook what you want it to do based on subtle differences in the amount of pressure you apply. This makes it possible to perform a variety of different actions in different apps, all on the same surface. And it can respond with haptic feedback you can actually feel, making your MacBook more usable and personal.
Traditional trackpads use a "diving board" mechanism, which requires room underneath for the downward motion of a click and makes it harder to click the part of the surface closest to the keyboard. With the Force Touch trackpad, force sensors detect your click anywhere on the surface and move the trackpad laterally toward you, although the feel is the same familiar downward motion you're accustomed to in a trackpad. The Taptic Engine also provides haptic feedback, so instead of just seeing what's happening on the screen, you can feel it, too. The trackpad sends a tangible response to your fingertip when you perform certain tasks, like aligning annotations on a PDF.
In addition to the intuitive Multi-Touch gestures you may be familiar with – like scrolling, swiping, pinching, and rotating – Force Touch brings an added dimension to the Mac experience. The sensitivity is customizable, allowing you to adjust how much pressure is needed to register a click. And the trackpad can even tell whether you're clicking with your thumb or another finger and automatically adjusts the sensitivity level.
Traditional keyboards use a scissor mechanism, which tends to wobble around the edges. This creates a lack of precision when you strike anywhere except the center of the key. Apple needed to reduce key wobbling for a keyboard this thin; otherwise, striking a key off-center could result in the keycap hitting bottom before a keystroke registers. So Apple designed a butterfly mechanism, which is wider than the scissor mechanism and has a single assembly made from a stiffer material – allowing for a more stable, responsive key that takes up less vertical space.
The redesigned keys on the MacBook feature a larger surface area, a thinner construction, and a deeper curvature, creating a more defined space for your fingertip to naturally find and press the keys. These refinements may be subtle, but the feel is distinct and intuitive. Combined with the butterfly mechanism, this innovative design allows for much greater control when typing.
Since the keyboard is thin, Apple had to address how to backlight the keys in a way that took up less space while delivering an even cleaner and more refined look and feel. To do that, Apple removed the row of LEDs and the light guide panel that distributed light throughout the keyboard and instead placed an individual LED under each key. These LEDs are calibrated for uniform brightness, so every key and character looks clear and sharp with minimal light around the keycap. All while being engineered for as much energy efficiency as possible.
