4K Retina Display 

The iMac 4K features an incredible 4K Retina Display. With a hugely detailed 4096 x 2304 resolution, it's the ideal screen for graphic design, editing photos and streaming the latest 4K films at their absolute best.

Whatever you do on a daily basis will look stunning.  


OS X El Capitan

The iMac runs on Apple's El Capitan operating system. Easy to navigate yet capable of professional-level computing, it provides a simple yet powerful platform for you to work, play and create the way you want to.

El Capitan has plenty of new features to make your Mac easier to use:

Split View fills the screen with two apps simultaneously for improved productivity and a more immersive work space. You can chat while you work on a presentation, keep an eye on social media and browse the web, or edit media with immediate reference to the source material. It works with any software, so the possibilities are endless.

Finding files is quick and easy no matter how many documents you have, or how unorganised you can be. Spotlight search now understands natural language, so you can ask it to find the presentation I made last Monday' or email from Martin in October that contains the budget.

iCloud is integrated into every aspect of El Captain, so you can share documents between all your Apple products and enjoy the peace of mind that comes with automatic backup and Time Machine compatibility. Plus, any notes you save are automatically shared between your Mac and mobile devices, which allows you to edit and add to documents whenever and wherever you want to. 

The latest Intel tech 

From editing photos to simply enjoying films and browsing the web, you can expect a powerful performance courtesy of quad-core Intel® Core™ i5 processing. Whether you're editing photos, working on a design project or simply typing an essay, you can get down to business without worrying about whether your Mac will keep up.

Intel® Iris™ Graphics give you improved visuals throughout all your daily computing. From games to graphic design, you can expect deep blacks, bright colours and fine detail that makes your media more immersive, your projects look their best and everyday computing sharp and engaging.

Space-saving design

Slim and built from Apple's signature aluminium alloy, the iMac 21.5 occupies minimal space and looks impressive in the office, studio or home. The design isn't entirely form over function either, as the IPS panel now sits flusher with the glass screen for improved clarity and reduced reflections.

Beautifully designed

The aluminium and glass case houses all you need for high-performance modern computing, including integrated WiFi, USB 3.0 and two Thunderbolt ports.

Magic Mouse and Keyboard

Included is the latest Magic Keyboard and Magic Mouse, the former of which features redesigned keys for increased comfort and more accurate typing.  

The Magic Mouse 2 has redesigned runners and still lets you gesture anywhere on the trackpad to move between pages, scroll and more.

You'll never have to fumble around looking for batteries again as both are rechargeable via Apple's Lightning cable. Just pop the cable in to charge - it only takes 2 minutes to add enough charge for 9 hours of use. Charge for longer to get around a month's worth of working.
