These iMac’s are in excellent condition and are ASD tested and refurbished by our own in house team of Apple Certified Technicians to work straight from the box, with a fresh installation of the Apple macOS High Sierra and come with a 12 month warranty, so you can buy with confidence.

The base model is 8GB / 240GB SSD, but you can configure to your own requirements using the drop-down fields to increase the RAM or have a larger SSD installed – its your choice!

Please also note that the SSD that you select to install will be a new unit, not the old, pre-existing one or a refurbished one, to give your unit that extra “works like new” touch.

All purchases from MacBank are supplied inclusive of 20% VAT, with an invoice to confirm.



21.5″ Display

The 21.5″ display with edge-to-edge glass covers nearly the entire front of the enclosure. When all you see is the display, nothing gets between you and what’s onscreen. Movies, TV shows, FaceTime HD video calls, websites, photos — everything looks stunning on the widescreen 16:9 iMac display.
LED Backlighting
The more pixels a display has, the more light those pixels need to achieve the best picture possible. And that’s exactly what the LED backlighting in iMac does: It pushes light through each pixel with remarkable brightness and efficiency. Because the LED backlight doesn’t take up much space, the iMac enclosure stays thin – even with all the high-performance components inside.
High Resolution
The 21.5″ iMac features 1920 x 1080 HD resolution. That’s equal to 1080p video — making the iMac an excellent choice for an HD editing workstation, video playback platform, and more!
Quad-Core Intel Processor
This iMac is powered by a quad-core Intel Core i5 processor. It is configured with DDR3 memory, and can be upgraded to handle as much as 16GB.
Advanced AMD Radeon HD Graphics
With advanced AMD Radeon HD graphics processors you see more frames per second in 3D games, and you can edit HD home videos with more speed and responsiveness than you ever thought possible.
Thunderbolt — Fast, Versatile I/O
Ultrafast and ultraflexible, the Thunderbolt port features two 10Gbps data channels for data transfer that’s up to 12 times faster than FireWire-800 and up to 20 times faster than USB 2.0. And it offers unprecedented expansion capabilities for a new generation of high-performance peripherals.
USB and FireWire
Bring on your iPad, iPod, digital camera, mobile phone, and external hard drive — there’s no shortage of ports on iMac. Four USB 2.0 ports and a FireWire-800 port give you plenty of peripheral possibilities.
Wi-Fi and Bluetooth
The dual-band 802.11n wireless technology in iMac makes it effortless to connect to a Wi-Fi network. iMac automatically finds available networks and lets you join them with a click. Bluetooth wireless technology is also built in, so you can use your favorite wireless accessories right out of the box.
Transfer photos and videos to your iMac as fast as you take them. The built-in SDXC card slot supports SD and SDHC cards with capacities up to 2TB. Just insert your camera’s memory card and import your photos to iPhoto.
Turbo Boost 2.0
Say you’re using a processor-intensive application like Aperture or Final Cut Pro that benefits from extra power. Turbo Boost 2.0 automatically increases the speed of the active cores — up to 3.3GHz. And by shifting core frequency in small increments, Turbo Boost allows the processor to manage performance without sacrificing efficiency. All this takes place behind the scenes, so your work (or play) goes smoother and faster.

Connectivity includes four USB 2.0 ports, a Firewire “800” port, built-in AirPort Extreme, Gigabit Ethernet, and an SDXC card slot as well as a single “Thunderbolt” port that is backwards compatible with Mini DisplayPort and, likewise, supports an external display up to 30″ (2560×1600). Thunderbolt also supports other peripherals that use the Thunderbolt standard that provides up to 10 Gbps of bandwidth in both directions.
