iMac (21.5-inch, 1.6GHz Intel Core i5, Late 2015)

The iMac (21.5-inch, 1.6GHz Intel Core i5, Late 2015) introduced in October 13, 2015, continues the mid-2014 iMacs line up, rather than that of the late 2014, namely – the iMac (21.5-inch, 1.4GHz Intel Core i5, Mid 2014). It has a faster processor, though the dual and not the quad core one, and neither Retina display nor Fusion Drive, nor a SSD storage. The dual core processor (Intel Core-i5 Ivy Bridge with Broadwell microarchitecture) has been upgraded to 1.6GHz. 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. There’s a bulge though in the center of the back panel to house all the hardware. The computer is mounted on an aluminum stand with a slightly tapered foot and an adjusting hinge.

The iMac (21.5-inch, 1.6GHz Intel Core i5, Late 2015) features a dual core 1.6GHz Intel Core i5 I5-5250U processor (Broadwell-U), with two independent processor cores on a single chip, DMI system bus and an integrated graphics core, 8 GB of RAM, a 1TB hard drive (5400 RPM), an SD memory slot card reader, an integrated Intel HD Graphics 6000 graphics with 1.5 GB of shared memory, a built-in FaceTime HD webcam and stereo speakers, as well as two “Thunderbolt-2” ports and 4 USB 3.0 ports. It also has built-in AirPort Extreme (802.11g) and Bluetooth 4.0. The cooling system is CPU controlled and the in-built speakers are mounted beneath the 21.5-inch screen for the clearer less distorted sound to bounce off the desk or other surface. The speakers’ grills also work as the vent ones. The iMac (21.5-inch, 1.6GHz Intel Core i5, Late 2015) is shipped with a compact aluminum Apple Wireless Keyboard and either with a “Magic Mouse” or a traditional wired Apple Mouse or a multi-touch Magic Trackpad.

Price, Discontinuation

  • Price: $1099.
  • Discontinued: June 5, 2017.


  • It’s a low-cost entry level iMac. The RAM upgrade is unintended, as well as that of a processor or an HDD, but a user can order the larger memory, the SSD storage and the faster processor at a time of order.
  • Keep in mind, the upgrade is impossible after system purchase at ll! Though technically Broadwell processors are better than Haswell ones, the U-letter means it has some cutbacks in performance. Thus, it cannot support more than 16 GB of RAM.
