iMac 21.5" 4K Retina Display

The vision behind iMac has never wavered: transform the desktop experience by fitting powerful, easy-to-use technology into an elegant, all-in-one design. The new iMac takes that idea to the next level — giving you even more amazing tools to do just about anything. iMac is packed with the latest processors, faster memory and phenomenal graphics. All coming to life on the brightest, most vibrant Retina display ever on a Mac. It’s the total package — powered up.

Retina Display

Show-stopping.
Eye-popping.

So bright and colourful, you can’t look away.

Available in stunning 4K or 5K, the Retina display shines beautifully on iMac. With a billion colours and 500 nits of brightness, graphics leap off the screen. Text is razor-sharp. Bingeworthy shows and blockbuster movies have never looked more amazing. Graphics and games dazzle in exquisite detail. It’s simply the best Mac Retina display yet.

500nitsbrightness

Amazingly true-to-life colour.

The world is full of spectacular colours, and iMac brings more of them to your screen. The Retina display uses P3 colour that shifts away from standard white LEDs to advanced red/green phosphor LEDs. That means all three colours — red, green and blue — are more equally represented and show off real-world colour with more balance and precision, bringing all your photos and content to life more vividly.

Performance

Quite the power couple.

Speed. From blazing-fast to breakneck.

Faster than ever, iMac is now equipped with eighth- and ninth-generation Intel Core processors and the latest in high-performance graphics options. Storage zips along too, with the snappy and spacious Fusion Drive available in both models. Or you can configure iMac with up to a 1TB SSD. So no matter what you’re into, you can do anything you love on iMac. All at maximum velocity.

Up to a whopping eight cores. Process that.

With ultrapowerful quad-core and all-new 6- and 8-core processors, iMac is a total tour de force. The 21.5-inch model reaches 4.6GHz. Which means you get more muscle when you’re using processor-intensive applications like Logic Pro X or Adobe Photoshop. Everything feels flat-out fast.

Up to 6-core eighth-generation Intel Core i7 processor
Up to 4.6GHz Turbo Boost
 

Graphics that render you speechless.

iMac features robust new Radeon Pro 500X Series graphics that make everything you see even more extraordinary. The 21.5-inch iMac with Retina 4K display ignites with up to 4GB. Both deliver visual effects and 3D graphics that exhibit raw power in its most polished form.

Bump it up to beast mode with Vega.

For even greater graphics performance, Radeon Pro Vega GPU options are now available on iMac. Vega — the same graphics architecture found in iMac Pro — delivers an enhanced compute engine and utilises High Bandwidth Memory (HBM2). This doubles the memory bandwidth to the GPU, resulting in sizzling performance. And it allows iMac to tackle graphics-intensive tasks like 3D rendering or complex video effects in a whole new (way faster) way.

Storage that’s lightning-fast. And quick on the uptake.

Storage is about space. But it’s also about speed. A Fusion Drive gives you the best of both worlds. The apps and files you use the most are automatically stored on fast flash storage, while everything else moves to a high-capacity hard drive. From booting up to launching apps to importing photos, it’s faster and more efficient to do it all with Fusion Drive. It comes standard on all 27-inch models, and as an option on the 21.5-inch model.

iMac + macOS

macOS is the operating system that powers everything you do on a Mac. It lets you do things you simply can’t with other computers. That’s because it’s designed specifically for the hardware it runs on — and vice versa. And the latest version, macOS Mojave, brings new features inspired by its most powerful users, but designed for everyone.

iMac + iPhone

Your iMac works seamlessly with your iPhone. So whether you’re texting, snapping a photo, or copying and pasting an image, you can move between devices without missing a beat.

Iconic design. Advanced engineering.
Talk about modern art.

iMac has always been the ultimate in form and function: an elegant, quiet, all-in-one computer that puts everything — display, processor, graphics, storage, memory and more — inside one simple, stylish enclosure. And thanks to its superslim profile, it fits in anywhere yet stands out everywhere.

Enclosure is 5mm thin at its edge
 
 

Packed with ports. And possibilities.

Two Thunderbolt 3 (USB-C) ports come standard on all iMac models, each delivering up to 40-Gbps data transfer for external drives and cameras, and ample bandwidth for video and display connectivity. Four USB 3 ports give you plenty of options for connecting peripherals, including your printer, iPhone, thumb drive and more. And with ultrafast three-stream Wi‑Fi and Bluetooth 4.2 wireless technology, you’re instantly connected to all your favourite content.
