The iMac Core i5 / 2.7 with 21.5” screen introduced in October, 2012, got the next generation state of the art quad core processor – Intel Core-i5 Ivy Bridge. This is the all-in-one desktop computer in an even slimmer all-aluminum unibody casing behind the 21.5” LED-backlit IPS screen with cover glass fully laminated to the LCD and anti-reflective coating. The body depth at its thinnest has 5 mm, though there’s a certain bulge in the center of the back panel. The computer is mounted on an aluminum stand with a slightly tapered foot and an adjusting hinge. The iMac “Core i5” 2.7 21.5” (late 2012) features a quad core 2.7 GHz Intel “Core i5 I5-3335S” processor (Ivy Bridge), with four independent processor cores on a single chip, DMI system bus and an integrated graphics core, 8 GB of RAM, a 1TB GB (5400 RPM) hard drive or an optional 1TB Fusion drive, an SD memory slot card reader, Nvidia GeForce GT 640M graphics with 512 MB of shared memory, a built-in FaceTime HD webcam and stereo speakers, as well as a “Thunderbolt” port 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” 2.7 21.5” (late 2012) is shipped with a compact aluminum Apple Wireless Keyboard and either with a “Magic Mouse” or a multi-touch Magic Trackpad.

- The Slim Unibody iMacs of late 2012 got the faster processor, the faster RAM and newer architecture.
- The Nvidia video chips had become the only graphics option.
- The hard drive capacity had been also increased while the rotation per minute speed decreased (for 21.5-inch models). Yet, Apple suggested a so-called Fusion drive (a hard drive with 128 GB of flash RAM) for customizing.
- The RAM upgrade is not intended, but the RAM modules aren’t soldered. It takes a lot of experience and accuracy though to unglue the screen and remove the logic board in order to get to the slots. There had been certain cutbacks in connectivity and multimedia. Thus, Apple had ditched an optical drive and a FireWire port.
- The USB 2.0 ports had been upgraded to USB 3.0 and Bluetooth 2.1 – up to 4.0 version.
