[A1419-I5-34-SSD-EXG] Apple iMac 27-inch - 3.4GHz Quad Core i5, 16GB RAM, 256GB SDD, Sierra OS, 6 Mth Wty (Refurbished)

A big, bold display. Fourth-generation Intel quad-core processors and the latest NVIDIA graphics. And much more. No desktop has ever brought so much to the table.

You won't want anything to distract you from what you’re viewing on these big, beautiful 21.5- and 27-inch displays. And nothing will, thanks to an amazing display design that reduces reflection by 75 per cent. In addition, because the LCD sits up against the glass, your content seems to leap off the screen.

The gorgeous iMac display looks great from any seat in the house. A technology called in-plane switching (IPS) gives you a bright picture with excellent colour from nearly any angle. And LED backlighting offers instant-on, uniform brightness with no waiting. So you’re always ready to share that holiday slideshow with the family.

Everything you see on the big, glossy display - from skin tones and dark shadows to bright blue skies and green fields - is rich and vibrant. And the colours are more true to life too. That's because every iMac display is individually colour-calibrated using state-of-the-art spectroradiometers to match colour standards recognised around the world.

Powered by fourth-generation Intel Core processors, this iMac is the fastest of this generation. Every model in the line-up comes standard with a quad-core Intel Core i5 processor, starting at 2.7GHz and topping out at 3.4GHz.

iMac graphics are more powerful across the board. NVIDIA GeForce 700 series graphics processors are even faster than the previous generation and include double the video memory. So you’ll see more frames per second in 3D games, and you can edit HD home videos with more speed and responsiveness than ever before. And you can get discrete-level performance in the 2.7GHz iMac with integrated Intel Iris Pro graphics.

For maximum performance, you can configure iMac with up to 1TB of flash storage (up to 512GB on the 21.5-inch iMac) instead of a traditional hard drive. This flash storage is now up to 50 percent faster than the previous generation3 and delivers up to 5x the performance of a traditional drive - speed you’ll notice when you start up your iMac, launch an app or browse your photo library.

iMac now supports ultrafast 802.11ac Wi-Fi. When it’s connected to an 802.11ac base station - including the new AirPort Extreme and AirPort Time Capsule - wireless performance is up to 3x faster than with the previous generation of iMac. And your Wi-Fi range improves as well.

Ultrafast and ultraflexible, the tiny Thunderbolt port offers unprecedented transfer speeds and incredibly versatile expansion capabilities. Connect high-performance peripherals such as external drives, cameras, audio and video capture devices - even Mini DisplayPort displays for more screen real estate. All iMac models include two Thunderbolt ports, so you can create the ultimate do-anything desktop.

Bring on your printer, digital camera, mobile phone and external hard drive. Every iMac comes with four USB 3 ports - with speeds up to 10 times faster than USB 2 - so you’ll have plenty of peripheral possibilities, including your iPhone or iPod, printer or Apple USB SuperDrive. And the USB 3 ports are fully compatible with your USB 2 devices.

Bluetooth 4.0 wireless technology is also built in, so you can use your favourite wireless accessories - such as the Apple Wireless Keyboard and Magic Mouse — straight out of the box.

Even though the iMac enclosure is thinner than ever, the built-in speakers deliver higher-fidelity sound than before. So when you’re listening to that new album, watching the latest flick or playing your favourite action game, you’ll get immersive sound and a surprisingly wide sound stage.

iMac has two built-in microphones that work together to home in on your voice and filter out the sounds around you. That means more accuracy when you’re using Dictation and better clarity during FaceTime video calls.

Get everyone in the picture with crisp, widescreen HD video. The built-in 720p FaceTime HD camera lets you make video calls that are so clear, it seems like everyone’s in the same room. Make FaceTime calls from your iMac to any FaceTime-enabled Mac, iPhone, iPad or iPod touch.

OS X Sierra takes full advantage of the incredible technologies in every Mac. It makes a powerful computer intuitive and easy to use. It makes Multi-Touch gestures on the trackpad feel fluid and natural. It makes it easy to find, organise, share and do just about everything. And thanks to iCloud, it makes your Mac, iPhone, iPad and iPod touch work wonderfully together.

iMac comes loaded with the iLife suite of apps: iPhoto for organising, editing and sharing your photos; iMovie for creating Hollywood-style movies at home; and GarageBand for making great music. You also get apps for sending email, managing your schedule and automatically backing up your Mac. There’s even an app for shopping for new apps at the Mac App Store.

iCloud stores your content and lets you access your music, photos, calendars, contacts, documents and more, from whatever device you’re on. So if you take a picture with your iPhone or make changes to your meeting schedule on your iPad, iCloud makes sure everything appears on your Mac too.

iMac is amazingly thin, yet it offers fourth-generation Intel Core processors, faster graphics, the advanced Fusion Drive and flash storage options, and ultrafast 802.11ac Wi-Fi. So it’s powerful enough for a design studio, production house or science lab. And beautiful enough for any room in your home.

The fourth-generation quad-core Intel Core i5 processor - based on the latest Haswell architecture — is standard on iMac. It’s available at a clock speed of up to 3.4GHz. Since OS X is designed to take advantage of each core, iMac captures every bit of performance from the processor.

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, Turbo Boost allows the processor to manage performance without sacrificing efficiency. All this takes place behind the scenes, so your work - and play - goes smoother and faster.

iMac graphics have gotten even more powerful across the board. NVIDIA GeForce 700 series graphics processors are faster than the previous generation and include double the video memory. That translates into more frames per second, smoother animation and better responsiveness when you’re using graphics-intensive apps like 3D games, high-resolution photo and video editors, and more. if you go with the 2.7GHz iMac, it comes with integrated Intel Iris Pro, which delivers discrete graphics-level performance.

With three-stream 802.11ac technology, iMac takes desktop Wi-Fi speeds over the top. When it’s connected to an 802.11ac base station — including the new AirPort Extreme and AirPort Time Capsule — you can reach data rates of up to 1.3 Gbps.4 That’s triple the previous 802.11n standard, which means you’ll get up to three times faster Wi-Fi.5 You also get double the channel bandwidth, with 80MHz-wide channels providing more room for more data to flow faster than ever.

With one tiny port, you get superfast data transfer speeds and huge expansion capabilities. Thunderbolt features two 10-Gbps data channels per port, which means data transfer is up to twice as fast as USB 3 and up to 12 times faster than FireWire 800. And don’t worry about a single drive or peripheral tying up a Thunderbolt port — you can daisy-chain as many as six devices plus a display. All iMac models include two Thunderbolt ports for even more expansion possibilities.
