21.5-inch and 27-inch displays.

The new iMac has come a long way from the first 15-inch iMac. Take one look and you’ll see just how far. A 21.5-inch or 27-inch display with edge-to-edge glass covers nearly the entire front of the enclosure. When all you see is the display, nothing gets between you and what’s onscreen. Movies, TV shows, websites, photos — everything looks stunning on the new 16:9 widescreen iMac display.

Evolution of iMac.

It was a great idea then, and it’s a great idea now. The all-in-one design of the first flat-panel iMac cleaned up the desktop. It put everything you need — display, processor, graphics card, hard drive, optical drive, memory, and more — inside one simple enclosure. New technology inside and out makes the new iMac a worthy addition to the all-in-one dynasty.

LED backlighting.

When a display has more pixels, you need to push more light through them to achieve the best picture possible. LED backlighting in the new iMac does exactly that, with remarkable brightness and efficiency. Because the LED backlight doesn’t take up much space, the iMac enclosure stays thin — even with all the high-performance components inside.

Seamless enclosure.

While you’ll find a collection of ports on the back of iMac, you won’t find much else. A seamless, precision-forged enclosure makes the back one continuous aluminum surface. And there’s only one cord: the power cord.

Higher resolution.

The new 21.5-inch iMac features 1920-by-1080 HD resolution. Apple engineers could simply have stretched that resolution up and out for the 27-inch iMac. Instead, they took the display well beyond HD with 2560-by-1440 resolution. That’s 78 percent more pixels than the 21.5-inch iMac.

IPS technology.

The iMac display is designed to look great from almost any angle. A technology called in-plane switching (IPS) makes this possible. Whether you’re sitting in front of the display or standing off to the side, you’ll get a perfect picture with superb color consistency and no loss of detail.

Cool, quiet components.

The wider iMac display allows more room to separate the two hottest components, the CPU and the GPU. This keeps things cool inside the iMac enclosure. Apple engineers also implemented an intelligent control system that monitors temperatures and delivers just the right amount of airflow to critical components. And the three fans inside iMac have been tuned to be ultraquiet. The result of all this tinkering with heat and sound? A system that operates at 18 decibels when idle — so quiet, you hardly know it’s on.

Edge-to-edge glass.

The glass that surrounds the LED-backlit display wraps around the edge of the aluminum enclosure.

Tapered pedestal.

Another victory over clutter, the finely tapered aluminum pedestal practically disappears on the desktop.

Redesigned speakers.

New speakers deliver louder, clearer sound with better bass response and less distortion.

Clutter-free wireless.

iMac embodies simple design that eliminates desktop clutter. So naturally, it’s the first Mac to come standard with the Apple Wireless Keyboard and the new wireless Magic Mouse.

Multi-Touch technology.

Magic Mouse is designed to do all the things a mouse should do — pointing, clicking, and scrolling — but with no scroll wheel, no trackball, and no visible button. Magic Mouse uses Multi-Touch technology to let you click, scroll, or swipe anywhere on its perfectly smooth, seamless top shell. But the real magic of Magic Mouse is how it knows what you want to do. A chip inside Magic Mouse acts as a brain, detecting the difference between a resting hand, a scrolling finger, a two-finger swipe, and a simple click. It’s the smartest mouse we’ve ever made.

LED backlighting. One bright idea.

Full brightness with no waiting. That’s the big advantage of the LED-backlit iMac display. Unlike most displays that take time to warm up before they reach maximum brightness, an LED-backlit display is instantly on and uniformly bright. LED backlighting also gives you greater control over screen brightness. So you can finely tune the iMac display to suit the ambient light in even the dimmest room.

More pixels. Better picture.

The new iMac offers some prime pixel real estate. The 21.5-inch, 1920-by-1080 display has 17 percent more pixels than the previous 20-inch iMac. The 27-inch, 2560-by-1440 display has a whopping 78 percent more pixels than the 21.5-inch iMac. And a 1000:1 contrast ratio gives you more vibrant colors and blacker blacks. All that in a widescreen display with a 16:9 aspect ratio — the same as an HD TV.

Stunning from every angle.

The new iMac display looks great from any seat in the house, thanks to a premium display technology called in-plane switching (IPS). IPS gives you a bright picture with excellent color consistency — even if you’re viewing the display from the side.

Now available with quad-core power.

The 21.5-inch and 27-inch iMac models offer fast Intel Core 2 Duo processors up to 3.33GHz. Quad-core power comes to the 27-inch iMac with a 2.66GHz Intel Core i5 processor or 2.8GHz Intel Core i7 processor. Four cores deliver up to 2x faster performance for just about everything you do: managing your photos, editing HD video, even playing graphics-intensive 3D games.¹ And since Mac OS X Snow Leopard is designed to take full advantage of Intel dual- and quad-core architectures, you get the fastest performance possible.

Revved-up graphics.

Every iMac comes with high-performance graphics that make games run smoother, photos load faster, and pro applications work better. If you want even speedier graphics, choose an iMac with a more advanced ATI graphics processor.

More memory and storage.

The new iMac has 4GB of 1066MHz DDR3 memory standard, with room in its four SO-DIMM slots for up to 16GB, so you can run more applications simultaneously. And with a Serial ATA hard drive up to 2TB, feel free to load up on photos, videos, and music.

Built-in Wi-Fi.

High-speed 802.11n wireless technology is built into iMac. And with Time Capsule or the AirPort Express Base Station, every computer in every room can wirelessly connect to iMac, the Internet, and each other. Over this network, everyone can print, surf the web, and play music on iTunes through your home stereo — wirelessly.

Wireless keyboard.

iMac banishes desktop clutter completely with a wireless keyboard to go with the wireless Magic Mouse. This low-profile keyboard takes up less desk space — 24 percent less — than larger keyboards. There’s no numeric keypad, so you can place your mouse comfortably next to the keyboard. And built-in Bluetooth means there are no cables to connect.

Wireless Magic Mouse.

Forget the mouse as you know it. Every iMac comes with the wireless Magic Mouse: the world’s first Multi-Touch mouse. Use it once and you’ll wonder how you ever used anything else. There’s no scroll ball, no clunky wheel, no cord, and no visible button.

Instead, Magic Mouse uses Multi-Touch technology to let you control everything with simple gestures. Give them a try and you’ll find that Magic Mouse changes the way you interact with your computer. Built-in software lets you configure Magic Mouse any way you want. Its smooth, seamless design is ambidextrous, and it supports two-button clicking — without buttons. Like magic.

Click

Click or double-click anywhere. The whole surface is a button.

Two-Button Click

Set up two-button click (right-click) in System Preferences.

360º Scroll

Scroll with one finger to move vertically and horizontally.

Screen Zoom

Hold down the Control key and scroll with one finger to magnify the screen.

Two-Finger Swipe

Swipe left and right with two fingers to go forward and back in Safari or iPhoto.

iSight camera

Look closely: Hidden behind the glass display at the top of iMac is an iSight camera. Use it with iChat, and you can be anywhere without actually being there. Video chat with up to three of your friends, share a video with a colleague, or present to a client. Use iSight with Photo Booth for fun photo effects. And there’s no need to waste valuable primping time installing software or configuring the camera. Like everything Mac, iSight just works.

Mini DisplayPort.

The Mini DisplayPort lets you connect an external display, including the Apple LED Cinema Display, to your iMac. On the 27-inch iMac, the same port offers input, too. So you can connect any external source that has DisplayPort output — including a MacBook or MacBook Pro — and use your iMac as a display.

SD card slot.

Transfer your photos and videos to and from your iMac just as fast as you’re able to take them. The new iMac has an SD card slot built in. Just insert your camera’s memory card and import your photos to iPhoto. From there, it’s easy to organize your photos by the people in them, share them online, or create photo books.

Wall mountable.

It’s easy to give your iMac a place of honor on the wall. The 27-inch iMac is compatible with the VESA Mount Adapter Kit for use with wall mounts and articulating arms.

USB and FireWire.

Bring on your iPod, digital camera, mobile phone, and external hard drive. If it has a cable, iMac has a port for it. Four USB 2.0 ports and a FireWire 800 port give you plenty of peripheral possibilities.

Quad-core power.

The available quad-core Intel Core i5 or Core i7 “Nehalem” processor in the 27-inch iMac puts four processing cores on one die, so data doesn’t have to travel far to get from core to core. This boosts application performance up to 2x over the previous-generation iMac. And unlike systems that connect memory to the processor through a separate controller, these quad-core processors connect memory directly to the processor, improving memory bandwidth up to 2.5x.

Turbo Boost.

A quad-core iMac also benefits from Turbo Boost. If you’re using an application that doesn’t need every core, Turbo Boost shuts off the idle cores while simultaneously increasing the speed of the active ones.

Built for more cores.

Mac OS X Snow Leopard is designed to take advantage of this advanced processor architecture, so every Intel processor reaches its full potential on iMac.

Options for everyone.

iMac offers graphics options designed to make the most of every pixel. Whether you’re an amateur filmmaker or an avid gamer, iMac gives you faster, smoother, clearer graphics across the board.

Start with advanced graphics.

The 21.5-inch iMac offers great graphics performance with the integrated NVIDIA GeForce 9400M graphics processor or the ATI Radeon HD 4670. The 27-inch iMac comes with dedicated high-performance ATI graphics across the line.

Upgrade to top-of-the-line graphics.

The ATI Radeon HD 4670 graphics processor delivers up to 4x faster performance than the NVIDIA GeForce 9400M — ideal for 3D games and graphics-intensive applications. For the ultimate in graphics performance, choose a 27-inch iMac with the ATI Radeon HD 4850 graphics processor.

Viewing and editing photos.

The new iMac is faster at importing photos and performing basic editing tasks — things like removing red-eye and erasing small blemishes — in iPhoto. If you’re a photo fanatic who loves the power and precision of more professional applications, the 2.8GHz quad-core iMac gives you up to 2x faster performance with Aperture.

Productivity.

iMac makes quick work of work. Create complex transitions in a Keynote presentation. Add 3D charts to a Numbers spreadsheet. Design a beautiful document in Pages. Powerful Intel processors across the iMac line make iWork fast and responsive.

Video editing.

Shot some video you want to edit fast and share with friends? Large iMac displays and powerful processors are perfect for editing and stabilizing shaky video in iMovie. For more complex editing and encoding tasks, upgrade to the 2.8GHz quad-core processor and get up to 2.3x faster performance with Final Cut Studio.

Playing games.

Games scream on iMac, thanks to advanced ATI graphics. The discrete ATI Radeon HD 4670 processor delivers up to 4.4x faster performance than the integrated NVIDIA GeForce 9400M processor. That’ll keep you on your game, even inside the complex 3D environments of Call of Duty 4 or Doom 3. Or choose the ATI Radeon HD 4850 processor for the ultimate in iMac graphics performance.

Perfect for everyday everything.

A Mac comes with everything you need for your email, calendar, contacts, browsing the Internet, and more. It’s all part of the Mac operating system: Mac OS X Snow Leopard. And if your daily routine includes watching movies and TV shows from iTunes, iMac brings entertainment to your desktop with a brilliant 16:9 widescreen display.

Hardware and software made to work together.

Apple makes the Mac, the software that comes with it, and the operating system that powers it. That makes features like the wireless Magic Mouse possible. Snow Leopard enables Multi-Touch gestures, so you can scroll with one finger or swipe with two.

Works with Windows.

The Mac also opens and works with Microsoft Office applications such as Word and Excel, and even runs Windows — so it’s compatible with the PC world. That includes sharing documents with people who use PCs, printing to just about any printer, and working over Windows networks.

Photos on a Mac.

iPhoto features face recognition technology that lets you organize your entire photo library by the people in the pictures. So when you want to find a particular photo of a friend, the hard work is already done for you.

Movies on a Mac.

With iMovie, you can put together a great-looking movie in minutes, then give it some professional polish. Add Hollywood-quality animated titles or stabilize shaky video in just a few clicks.

Making music on a Mac.

A Mac can teach you how to play guitar or piano. Open GarageBand and you’ve got video music instruction right on your Mac. You can even download Artist Lessons, and learn to play hit songs from the musicians who made them famous.

Don’t worry about viruses.

Designed with security in mind, Mac OS X Snow Leopard isn’t plagued by constant attacks from PC viruses and malware. Every Mac is highly secure right out of the box, so you can safely go about your work — or play — without interruption.

On guard.

Innocent-looking files downloaded over the Internet may contain dangerous malware in disguise. That’s why files you download using Safari, Mail, and iChat are screened to determine if they contain applications. If they do, Mac OS X Snow Leopard alerts you, then warns you the first time you open one.

Always up to date.

When a potential security threat arises, Apple responds quickly by providing software updates and security enhancements that can be downloaded automatically and installed with a click.

The latest technology.

Intel dual-core or quad-core processors are standard on every Mac, so applications fly. Powerful graphics bring the latest 3D games to life. And an iSight camera, Bluetooth, and many other features are all built in.

Features you won’t find on a PC.

On a Mac, innovation extends to features you might not expect. Like a desktop computer with only one cord — the power cord. iMac reduces desktop clutter by including the Apple Wireless Keyboard and wireless Magic Mouse standard. So out of the box, you get the most streamlined computer experience possible.

The world’s most advanced operating system.

Every Mac comes with Mac OS X Snow Leopard, an operating system custom-made for the advanced technology inside. Built on a rock-solid UNIX foundation and designed to be simple and intuitive, it’s what makes the Mac innovative, highly secure, compatible, and easy to use.

Energy efficiency.

Because Apple designs both hardware and software, we can reduce our environmental footprint in ways others can’t. For starters, a highly efficient power supply reduces the amount of power wasted when bringing electricity from the wall to your Mac. Unlike a lot of PCs, a Mac uses energy-efficient hardware components that work hand in hand with the operating system to conserve power — even between keystrokes.

Fewer toxic substances.

A Mac doesn’t contain a lot of toxic materials. All Mac displays are mercury and arsenic free, and the internal components are free of polyvinyl chloride (PVC) and brominated flame retardants (BFRs).

Recyclability.

When a Mac reaches the end of its long life, the materials it’s made from — like aluminum and glass — make it highly desirable to recyclers. And you can recycle your old computer free when you buy a new Mac.
