The iMac Core i5 / 1.6 with 21.5” screen introduced in October 13, 2015, continues the mid-2014 iMacs line up, rather than that of the late 2014, namely – the iMac “Core i5” 1.4 21.5-Inch (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 1.6 GHz. 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” 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 “Core i5” 1.6 21.5” (late 2015) features a dual core 1.6 GHz 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” 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 “Core i5” 1.6 21.5” (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.

Apple Order number: MK142LL/A.
- 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.
