MagSafe and more. Much more.

MagSafe and more. Much more.

Even the power cord is an innovation.

The MagSafe Power Adapter has a magnetic connection instead of a physical one. So if someone happens to trip over the power cord while you’re working, they won’t send your new MacBook flying off a table or desk. Instead, the cord breaks cleanly away, without damage to either the cord or the system. As a bonus, you can tell if your MacBook is fully charged when the LED on the connector changes from amber to green.

Wireless that works.

If you’ve previously connected to a network, your Mac automatically logs you in so you can immediately email, surf the web, or video chat.⁶ Have a phone, headset, keyboard, or mouse with Bluetooth wireless technology? They can all connect to your MacBook courtesy of built-in Bluetooth 2.1 + EDR technology — and it remembers all your devices, too.

Productivity expert.

With a fast 2.26GHz Intel Core 2 Duo processor, MacBook breezes through everyday tasks such as emailing, web browsing, and working with documents, spreadsheets, and presentations in iWork or Microsoft Office for Mac (sold separately). It also provides plenty of horsepower for more processor-intensive activities such as retouching a photo in iPhoto, editing an iMovie project, and composing a new song using GarageBand, so you can make the most of the included iLife suite of applications. It even runs Microsoft Windows at native speeds. Better still, MacBook comes standard with 2GB of memory (with support for up to 4GB), so you can run multiple applications smoothly and efficiently.

Multi-Touch comes to MacBook.

Multi-Touch comes to MacBook.

More room to navigate,
more ways to interact.

The first thing you might notice — or not notice — about the new MacBook Multi-Touch trackpad is the button. The entire trackpad is the button, so you can click anywhere on the touch-friendly glass surface. Not having a separate button also makes for a larger trackpad surface, giving your fingers more room to move, click, and gesture. And because the trackpad supports Multi-Touch gestures, you can use one or more fingers to interact with your documents, images, and applications with gestures such as two-finger scroll, pinch, swipe, and rotate. If you come from a right-click world, you can configure a right-click area on the trackpad or simply press with two fingers.

Using the Multi-Touch Trackpad

Perform gestures on a spacious and smooth Multi-Touch trackpad that’s also the button.

One-finger click

The longest-lasting MacBook battery ever.

The longest-lasting MacBook battery ever.

Up to 7 hours per charge, up to 1000 recharges.

Now take MacBook with you everywhere without worrying about plugging in or even carrying your power adapter. Its built-in lithium-polymer battery lasts up to 7 hours on a single charge,¹

which makes it perfect for long flights, all-day workshops, and marathon study sessions. Thanks to its advanced battery chemistry and charging technology, the MacBook battery can be recharged up to 1000 times — good for about five years of typical usage — and lasts nearly three times the lifespan of typical notebook batteries.² That makes for less waste. And that, in turn, makes for one environmentally friendly battery.

An LED-backlit display of brilliance.

An LED-backlit display of brilliance.

A 13.3-inch glossy widescreen.

The moment you open your new MacBook, its glossy LED-backlit display greets you with glorious, full-screen brightness and brings your photos, movies, and presentations alive with luminous color. The widescreen resolution of 1280 by 800 pixels gives you plenty of room to multitask, yet it’s compact enough to take anywhere. And the display is greener than ever: power efficient, free of harmful toxins such as mercury, and made of arsenic-free glass.

Clean, simple interior design.

MacBook is as well designed on the inside as on the outside. Turn it over and you’ll notice a seamless, sturdy, single-piece bottom case with no battery compartment. That’s because the lithium-polymer battery in the new MacBook is strategically built right into the enclosure. In addition to providing extra overall durability, this integrated design eliminates the space-consuming parts required by a removable battery. This allows more room for a larger-capacity battery that can run up to 7 hours on a single charge² — all in an enclosure that is just as thin and even lighter. When you remove the bottom case, you’ll discover a clean, simple interior layout that makes it easy to add more memory or a larger hard drive.

Easy access to connections and ports.

The connections and ports on MacBook — MagSafe power, Gigabit Ethernet, Mini DisplayPort, USB, and audio in/out — are all smartly integrated on the same side of the notebook. So your cables stay neatly organized, and connecting and disconnecting your devices is easy and convenient.

Spacious glass Multi-Touch trackpad.

Spacious glass Multi-Touch trackpad.

The new MacBook Multi-Touch trackpad has no button because it is the button. That means there’s plenty of room to move your fingers around, and you can click anywhere — left, right, center, and everywhere in between. The trackpad features a silky smooth glass surface that feels great to the fingertips. Use it to perform familiar functions such as right-click or two-finger scroll as well as Multi-Touch gestures: pinch to increase font size in a document, rotate your fingers to reorient photos, swipe to navigate through web pages, and more.

A comfortable keyboard your fingers will love.

MacBook portability doesn’t happen at the expense of key features. The keyboard is full size, with keys that are curved to contain your fingers and highly responsive to your touch. Its low-profile design integrates perfectly into the unibody enclosure, so you’ll get a comfortable experience whether you’re typing a quick email or writing a lengthy research report. The keyboard also gives you one-touch access to music and video controls and Mac OS X features such as

Quality screen time.

MacBook now features an LED-backlit 13.3-inch glossy widescreen display for an even more spectacular viewing experience. Documents, videos, photos, and games look incredibly sharp and detailed. The LED backlighting delivers stunning colors and instant full-screen brightness the moment you open the lid. And its 1280-by-800 pixel resolution offers an outstanding balance of luminous color and easy readability in a perfectly portable size.

Durable unibody enclosure.

A mere 1.08 inches thin and even lighter at 4.7 pounds,¹ the sleek new MacBook cuts a slim profile on any desk (or in any backpack or briefcase). It features a new seamless, more durable unibody enclosure with rounded contours that make it easy to pick up and slide into and out of your bag. And it’s made of rugged polycarbonate that withstands the rough and tumble of everyday life — at school, at work, or while traveling. Even the bottom of the new MacBook feels different. Covering its entire surface is a nonslip material that keeps your MacBook right where you put it, whether on a desk, table, or airplane tray.
