Apple A Grade Desktop Computer 21.5-inch iMac A1418 2017 MNE02LL/A 3.6 GHz Core i7 (I7-7700) 16GB RAM 2TB HDD & 128 GB SSD Storage Mac OS Include Keyboard and Mouse

The iMac "Core i7" 3.6 21.5-Inch Aluminum (Retina 4K, Mid-2017/Kaby Lake) technically is a "configure-to-order" configuration of the iMac "Core i5" 3.0 21.5-Inch (4K, Mid-2017) or iMac "Core i5" 3.4 21.5-Inch (4K, Mid-2017), but also is documented as a separate model for reader convenience. Other than processor (and the corresponding level 3 cache), this model can be configured identically to its standard issue brethren.

The iMac "Core i7" 3.6 21.5-Inch Aluminum (Retina 4K, Mid-2017/Kaby Lake) features a 14-nm "Kaby Lake" 3.6 GHz Intel "Core i7" processor (7700) with four independent processor "cores" on a single chip, an 8 MB shared level 3 cache, 8 GB of 2400 MHz DDR4 SDRAM that is reportedly onboard -- but actually can be upgraded later -- ether a 1 TB hard drive or a 1 TB "Fusion" drive that combines a small SSD and a 1 TB hard drive, and either a Radeon Pro 555 or 560 graphics processor with 2 GB or 4 GB of dedicated VRAM, respectively. It also has a built-in "FaceTime HD" webcam and stereo speakers.

This model has a 21.5" 4096x2304 LED-backlit 16:9 widescreen IPS DCI-P3 "Retina 4K" display (that runs "pixel doubled" to look like 2048x1152). The rear of the case is aluminum and is thicker in the middle and tapers to a razor thin 5 mm at the edges.

Connectivity includes four USB 3.0 ports, dual Thunderbolt 3 (USB-C) ports, Gigabit Ethernet, 802.11ac Wi-Fi, and Bluetooth 4.2.

Compared to its predecessor, this model essentially has the same external enclosure, but it has a more advanced processor and architecture as well as dedicated graphics, a brighter display, and Thunderbolt 3 (USB-C) ports.

By default, the "Mid-2017" iMac models shipped with a compact aluminum Apple Magic Keyboard and the multi-touch "Magic Mouse 2". For an additional US$30, you could upgrade from the default keyboard to the "Magic Keyboard with Numeric Keypad" and for an additional US$50, you also could upgrade from the Magic Mouse 2 to the "Magic Trackpad 2," which provides multi-touch and pressure-sensitive "Force Touch" capabilities.
