The iMac desktop supplies computer greatness no matter where you are working. 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. All of this adds up, giving you the most immersive Apple iMac computer experience yet — and another big, beautiful step forward.
