iMac Retina. Now in colossal and ginormous.

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.

OS X. It’s what makes a Mac a Mac.

OS X is the operating system that powers every Mac. Built on a rock-solid UNIX foundation, it’s engineered to take full advantage of what the hardware is capable of. It’s designed to be as easy to use as it is beautiful to look at. It comes with an amazing collection of apps you’ll use — and love — every day. And it enables your Mac and iOS devices to work wonderfully together.

Easy to learn. Easy to use.

On a Mac, it’s easy to find, share, and do just about everything. You can control your Mac with simple, intuitive gestures. The Dock lets you launch your favorite apps with a click. Launchpad gives you quick access to your full library of apps. The Finder lets you browse and organize your files on your Mac and in iCloud with ease. Spotlight search makes locating documents, launching apps, and looking up information effortless. You can even have your apps and the operating system software update automatically. In fact, a Mac does so many things automatically, sometimes you don’t have to do anything at all.

Software and hardware made for each other.

OS X is built to bring out the best in your Mac, so you get a fully integrated system in which everything works together seamlessly. It works with the processor and graphics controller in your Mac to deliver the best possible performance. It works with the super-responsive trackpad in Mac notebooks so Multi-Touch gestures feel natural to use. OS X even keeps your Mac up to date while it sleeps. Advanced power-saving technologies help extend battery life. And in OS X El Capitan, new system fonts are designed to look crisp and vivid on high-resolution Retina displays.

One of the best things about a Mac is everything you can do with it.

Every Mac comes with a collection of great apps for things you do every day, like Safari for sur?ng the web, Photos for managing your photos and videos, Pages for creating documents, Numbers for making spreadsheets, and Keynote for preparing presentations. There are apps for sending email and text messages, taking notes, and staying up to date with your contacts and calendar. It even comes with the Mac App Store for finding new apps. Your Mac is more than fully featured, it’s fully loaded.

Apple Accessories: Redesigned. Rechargeable. Remarkable.

The all-new Magic Keyboard, Magic Mouse 2, and Magic Trackpad 2 have been redesigned to make every interaction feel amazing. From a built?in rechargeable battery to a new lower profile, they’ve been enhanced to deliver more comfort and functionality than ever before. Paired with iMac, they work magic together.
