The idea behind iMac has never wavered: to craft the ultimate desktop experience. The best display, paired with high-performance processors, graphics, and storage – all within an incredibly thin, seamless enclosure. And that commitment continues with the all-new 21.5-inch iMac with Retina 4K display. Like the revolutionary 27-inch 5K model, it delivers such spectacular image quality that everything else around you seems to disappear. Adding up to the most immersive iMac experience yet – and another big, beautiful step forward.

Retina Display

More than just a display, it’s a vision.

Accuracy. Brightness. Clarity. Regardless of how you measure the quality of a display, Retina is in a class by itself. The pixel density is so high that you won’t detect a single one while using iMac. Text is so sharp, you’ll feel like you’re reading email and documents on a printed page. And with a new, wider color gamut, the Retina display is able to deliver even more available colors – 25 percent more. So every photo and video you see appears even more true to life.

Design

Innovation from edge to cutting edge.

An incredible amount of engineering was required to bring the Retina display to the iMac family. Witness a design that’s just 5 mm at its edge – yet entirely capable of making everything around you fade into the distance. This ensures that nothing gets between you and your favorite content. Seamless and beautiful, iMac with Retina display is an elegant addition to your workspace, representing a depth of technology at the height of design.

Fusion Drive

Storage that’s lightning fast. And whip smart.

Storage is about space. But it’s also about speed and performance. A Fusion Drive gives you the best of both worlds. This innovative storage technology intelligently combines speedy flash storage with a high-capacity hard drive. Your frequently used apps, documents, and photos stay on the faster flash storage, while infrequently used items move to the hard drive. And as the system learns how you work, you’ll experience faster application launching and quicker file access. Fusion Drive can be configured with up to 3TB of storage. But for those who want the ultimate performance, there’s an all-flash option that’s now up to 2.5 times faster than the previous version.

Performance

Built for speed. And everything else.

Faster and more powerful than ever, the 27-inch iMac is equipped with a sixth-generation Intel Core processor and the latest AMD high-performance graphics. And the 21.5-inch iMac features a fifth-generation Intel Core processor and enhanced Intel Iris Pro Graphics. Both deliver stirring visual effects with maximum impact – at maximum speed.

Connectivity

Fast connections for high performance.

iMac is astonishingly thin. But it’s jam-packed with advanced technology. Two Thunderbolt 2 ports come standard on all iMac models and deliver blazing-fast data transfer for external drives and cameras. Four USB 3 ports give you plenty of options for connecting peripherals, including your printer, video devices, and more. And with ultrafast three-stream Wi-Fi and Bluetooth 4.0 wireless technology, you’re instantly connected to all your favorite content.

OS X El Capitan

The world’s most advanced desktop operating system.

OS X is what makes a Mac a Mac. Not only is it designed to be intuitive and easy to use, but it’s also engineered to take full advantage of the Retina display, so you’ll see everything on your desktop with stunning clarity. It features an incredible collection of apps you’ll use – and love – every day. And it’s designed to enable your Mac and iOS devices to work together in amazing ways.
