Apple 12″ MacBook 2015- MK4M2LL/A with Retina Display- Gold

Pure invention.We designed the new MacBook to be not only thinner and lighter, but more functional and intuitive than ever before. To do that, we couldn’t just shave a millimeter here, a gram there. So we started from scratch, reinventing each essential element as part of a singular, deceptively simple design. It’s everything there is to love about Mac. In its purest form ever. A keyboard re-imagined from A to Z.From the beginning, our goal was to design a full, uncompromising Mac experience. And a full-size keyboard is an essential part of that. In order to fit a full-size keyboard in the incredibly thin MacBook, we designed the keyboard from the ground up. Each component has been rethought specifically for the new MacBook, from the underlying mechanism to the curvature of the surface of each key to the distinctive new typeface. The result is a keyboard dramatically thinner than its predecessor. Now when your finger strikes the key, it goes down and bounces back with a crisp, consistent motion that makes typing with precision a breeze.
Butterfly mechanism 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. We needed to reduce key wobbling for a keyboard this thin; otherwise, striking a key off-center could result in the key-cap hitting bottom before a keystroke registers. So we designed an entirely new 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. This innovative design improves stability, uniformity, and control — no matter where you press on the key.
Key designThe redesigned keys on the new 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 new design allows for much greater control when typing.0.88 millimeter. Razor sharp.The 12-inch Retina display on the new MacBook isn’t just picture perfect — it’s also paper thin. In fact, at just 0.88 millimeter, it’s the thinnest Retina display ever on a Mac. A specially developed automated manufacturing process forms the impossibly thin edge-to-edge glass that’s only 0.5 millimeter thick. And we reduced the space between display components for a tighter, more integrated design.To deliver the gorgeous Retina experience on the sleek new MacBook, we had to innovate on every level, right down to the pixel. So we redesigned the pixels to create a larger aperture, allowing more light to pass through. This enabled us to use LED back lighting that’s 30 percent more energy efficient than the Retina display on any other Mac notebook, yet still achieve the same level of vivid brightness. The Force Touch trackpad.Press a little deeper, do a lot more.The new Force Touch track pad may look like other track pads on the surface, but underneath it’s unlike anything that’s existed before. Force sensors detect how much pressure you’re applying, and the new Tap tic 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 track pad 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 hap tic feedback you can actually feel, making your MacBook more usable and personal than ever before.
Tap tic Engine Traditional track pads 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 track pad, force sensors detect your click anywhere on the surface and move the track pad laterally toward you, although the feel is the same familiar downward motion you’re accustomed to in a track pad. The Tap tic Engine also provides hap tic feedback, so instead of just seeing what’s happening on the screen, you can feel it, too. The track pad sends a tangible response to your fingertip when you perform certain tasks, like aligning annotations on a PDF.
Force Touch-In addition to the intuitive Multi-Touch gestures you may be familiar with — like scrolling, swiping, pinching, and rotating — Force Touch brings a new dimension to the Mac experience. The sensitivity is customizable, allowing you to adjust how much pressure is needed to register a click. And the track pad can even tell whether you’re clicking with your thumb or another finger and automatically adjusts the sensitivity level.
