Apple has unveiled the 27-inch iMac with Retina 5K display, featuring the world’s highest-resolution display — with 14.7 million pixels. At this resolution, text appears sharper than ever, videos are more lifelike, and you can see new levels of detail in photos. “Thirty years after the first Mac changed the world, the new iMac with Retina 5K display running OS X Yosemite is the most insanely great Mac we have ever made,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing. “With a breathtaking 14.7-million-pixel display, faster CPU and graphics, Fusion Drive, and Thunderbolt 2, it’s the most beautiful and powerful iMac ever.”
