iMac (21.5-inch Retina 4K, 3.1GHz Intel Core i5, Late 2015)
The iMac iMac (21.5-inch Retina 4K, 3.1GHz Intel Core i5, Late 2015) introduced in October 13, 2015, is almost identical to the iMac (21.5-inch, 2.8GHz Intel Core i5, Late 2015). It has a quad processor of enhanced microarchitecture plus Retina 4k display, but neither Fusion Drive, nor an SSD storage. The design is similar to the iMacs of 2012. This is the all-in-one desktop computer in an ultra-thin (5 mm depth at the edges) all-aluminum unibody casing behind the 21.5-inch LED-backlit IPS screen with cover glass fully laminated to the LCD and anti-reflective coating.
