The fastest; most powerful MoacBook Pro ever . Times three.

The new 15- and 17-inch MacBook Pro.

New Intel Core i5 and Core i7 processors.

The new Intel Core i5 and Core i7 processors boost performance up to 50 percent over the previous generation. Based on Intel’s latest 32-nanometer process technology, these are the fastest dual-core processors available and they set an all-new benchmark for Mac notebooks.¹

Precision aluminum. The new gold standard.

Carved from a single block of aluminum, the MacBook Pro is a true engineering achievement. Its patented unibody enclosure is the product of precise machining. From the thumbscoop to the now-you-see-it-now-you-don’t sleep indicator, no detail is unaccounted for. The end result is a notebook that’s not only breakthrough, but thin, light, polished, and refined. The unibody also makes MacBook Pro more durable than ever. So you can throw it in your briefcase or messenger bag and pull it out at an airport, at school, at the office, or on location without a second thought.

Until now, all notebooks were designed the same way. By assembling multiple pieces to create a single enclosure. But once you include all the necessary parts, you add size, weight, complexity, and more opportunities for failure. Solving a problem like this required more than an incremental change. It required a breakthrough. To create the MacBook Pro, the design and engineering teams devised a way to replace many parts with just one. That one part is called the unibody — a seamless enclosure carved from a single piece of aluminum.

Unibody Enclosure

The MacBook Pro starts life as a single piece of aluminum. View

Of course, building only one part creates its own set of challenges. When you have multiple parts that are fastened together, tolerances don’t need to be perfect. You have wiggle room, both literally and figuratively. But when one part is responsible for many functions, it’s critical to manufacture that part with absolute precision, down to the micron. Every time. Millions of times over. There was only one way to achieve this level of precision: mill the unibody from a solid block of aluminum using computer numerical control, or CNC, machines — the kind used by the aerospace industry to build mission-critical spacecraft components.

When you pick up a MacBook Pro, you immediately notice the difference. The entire enclosure is thin and light. It looks polished and refined. And it feels strong and durable — perfect for life inside (and outside) your briefcase or backpack.
