The 27-inch iMac with Retina 5K display is a Mac through and through — with powerful technologies, incredible performance, the world’s most advanced desktop operating system, and amazing built-in apps. And with a remarkable5120-by-2880 resolution, you’ll experience everything on your display like never before.
A true work of art. And physics.
Precision and innovation have always been a part of the iMac story. Bringing the Retina 5K display to the 27-inch iMac was no different. It meant making incredible leaps in design at every level — from reengineering the brains of the display to maintaining 1/100th of a micron tolerances within the display cell. Not to mention fitting four times as many pixels — and the power to drive them — inside. All without compromising the amazingly thin iMac design.
OS X. It’s what makes a Mac a Mac.
OS X is the operating system that powers every Mac. Built on a rock-solid UNIX foundation, it’s engineered to take full advantage of what the hardware is capable of. It’s designed to be as easy to use as it is beautiful to look at. It comes with an amazing collection of apps you’ll use — and love — every day. And it enables your Mac and iOS devices to work wonderfully together.
One of the best things about a Mac is everything you can do with it.
Every Mac comes with apps for creativity and apps for productivity. It also comes with a collection of great apps for things you do every day, like surfing the web, sending mail and messages, and organizing your calendar. It even comes with an app for finding new apps. Your Mac is more than full‑featured, it’s fully loaded.
