Apple introduced the first iMac more than a decade ago. And the design philosophy remains the same:
an all-in-one computer that’s as powerful as it is beautiful.
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.
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.
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.
PS 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 colour consistency and no loss of detail.
... 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.
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 aluminium surface. And there’s only one cord: the power cord.
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.*
The glass that surrounds the LED-backlit display wraps around the edge of the aluminium enclosure.
Another victory over clutter, the finely tapered aluminium pedestal practically disappears on the desktop.
Redesigned speakers.
New speakers deliver louder, clearer sound with better bass response and less distortion.
iMac comes standard with a wireless keyboard and the new Magic Mouse.
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 colours 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 colour 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 i3 processors up to 3.2GHz. Quad-core power comes to the 27-inch iMac with a 2.8GHz 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,² 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 theAirPort Express Base Station, every computer in every room can wirelessly connect to iMac, the Internet, and each other.³ Over this network, everyone can print, surf the web, and play music on iTunes through your home stereo — wirelessly.
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.
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.
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.
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.
Ports for everything. And then some.

On every Mac...
Highly secure and reliable, a Mac is built on Mac OS X Snow Leopard: the world’s most advanced operating system. And every Mac comes with software that lets you do more with photos, movies, and music.
With available quad-core processors and advanced graphics, the new iMac is the fastest, most powerful iMac yet.
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.
