Ex-Display Apple iMac 21.5-inch 4K Retina 8GB/1TB


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. 


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 colour gamut, the Retina display is able to deliver even more available colours — 25 per cent more. So every photo and video you see appears even more true to life.


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 5mm at its edge — yet entirely capable of making everything around you fade into the distance. This ensures that nothing gets between you and your favourite 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.


Storage that’s lightning fast. And super 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.1 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.


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.


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.


Fast connections for high performance.
iMac is astonishingly thin. But it’s jam-packed with advanced technology. Two Thunderbolt 2 ports come as standard on all iMac models and deliver incredibly 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 ultra-fast three-stream Wi‑Fi and Bluetooth 4.0 wireless technology, you’re instantly connected to all your favourite content.


macOS - It’s why there’s nothing else like a Mac.
macOS is the operating system that powers everything you do on a Mac. macOS Sierra introduces Siri to Mac — along with new ways to enjoy your photos, shop more securely online and work more seamlessly between devices.


Our best built-in apps. The best they’ve ever looked.
Every new Mac comes with Photos, iMovie, GarageBand, Pages, Numbers and Keynote. So you can be creative right from the start. You also get great apps for email, surfing the web, sending texts and making FaceTime calls — there’s even an app for finding new apps.


Everything you love on your iMac. On all your devices.
iCloud stores your content and lets you access your music, photos, calendars, contacts and more from whatever device you’re using. And with iCloud Drive, you can safely store all your presentations, spreadsheets, PDFs, images and any other kind of document in iCloud — and access them from your iPhone, iPad, iPod touch, Mac or PC.
