Refurbished 21.5-inch iMac 3.2GHz 6-core Intel Core i7 with Retina 4K display and Radeon Pro Vega 20

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.

Available in stunning 4K or 5K, the Retina display shines beautifully on iMac. With one billion colors and 500 nits of brightness, graphics leap off the screen. Text is razor-sharp. Binge-worthy 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.

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

For even better performance, this model comes with the Radeon Pro Vega 20 with 4GB of HBM2 memory. Featuring advanced Vega architecture with second-generation High Bandwidth Memory integrated on the GPU package, this GPU delivers fast graphics performance — accelerating video editing, 3D workflows and game development.

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.

Two Thunderbolt 3 (USB-C) ports come standard on all iMac models, each delivering up to 40Gb/s 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 favorite content.

Your Mac works with your other Apple devices in ways no other computer can. If you get a call on your iPhone, you can take it on your Mac. With Continuity Camera, you can use your iPhone to take a picture or scan a document nearby, and it will appear right on your Mac. When you copy text or an image from one device, you can paste it into another with standard copy and paste commands. You can even unlock your Mac with your Apple Watch. No password typing required.

macOS is the operating system that powers every 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. macOS comes with an entire suite of beautifully designed apps. It works hand in hand with iCloud to keep photos, documents, and other stuff up to date on all your devices. It makes your Mac work like magic with your iPhone. And it’s been built from the ground up with privacy and security in mind.
