Apple has updated the entire iMac family, bringing a new Retina 4K display to the 21.5-inch iMac for the first time and the Retina 5K display to every 27-inch iMac.
The new Retina displays make photos and videos more immersive and true-to-life thanks to a wider colour gamut and spectacular image quality. The updated iMacs also feature more powerful processors and graphics, two Thunderbolt 2 ports and new storage options that make the high-performance Fusion Drive even more affordable.
Apple also introduced a new lineup of wireless accessories including the all-new Magic Keyboard, Magic Mouse 2 and Magic Trackpad 2. The Magic devices have been redesigned to feel more comfortable than ever, and feature rechargeable batteries that completely eliminate the need for disposable batteries. The new Magic Trackpad 2 also brings Apple’s revolutionary Force Touch interface to the desktop, adding a new dimension to the iMac experience.
very new Mac comes with OS X El Capitan.
