About this imac

About macOS on this Mac

This Mac ships with macOS Ventura (13) installed and ready to use. Ventura runs all the everyday software you'd expect — current Microsoft Office for Mac (Word, Excel, PowerPoint, Outlook), Google Chrome, Safari, Microsoft Teams, Zoom, Spotify, and the Mac App Store.

A note about how Ventura is installed: Apple stopped issuing new macOS releases for this model. We've installed Ventura using OpenCore Legacy Patcher (OCLP), a respected community tool that lets older Macs run modern macOS. The Mac boots, performs and behaves like any other Ventura installation.

Important — please do not attempt to update macOS. Apple does not ship Ventura updates to this model, so the System Settings → Software Update dialog won't work as expected. Updates require re-running OpenCore, which we're happy to handle for you. Trying to update through Software Update may fail or leave the system in an inconsistent state.

One small thing to expect: very occasionally an Apple service such as iCloud, FaceTime, or Messages may ask you to re-authenticate. This is normal for OCLP-installed Macs and signing in again resolves it.

The refurbished Apple iMac 21.5" (2015) delivers the classic all-in-one Mac desktop experience with powerful Intel Core i5 or i7 processors, 16GB of RAM, and your choice of storage configurations from 256GB SSD through to 2TB HDD. Launched in 2015, this iMac remains a capable machine for everyday computing, office work, creative projects, and media consumption. With its stunning Retina 4K display and sleek aluminium design, it brings Apple's signature quality to home offices, student desks, and family spaces. Available from £150 in Grade A, B, or C condition, each unit has been professionally refurbished, tested, and ships with macOS Ventura ready to use straight out of the box.

Choose from configurations with either the Intel Core i5-5575R or the Intel Core i7-4771 and i7-5775R processors, all quad-core chips that handle multitasking, web browsing, Microsoft Office, video calls, and light creative work with ease. Every unit comes with 16GB of RAM, giving you plenty of headroom for running multiple applications simultaneously. Storage options span from fast 256GB and 1TB SSDs for snappy boot times and application launches, through to 1TB Fusion drives that blend SSD speed with HDD capacity, and cost-effective 1TB or 2TB hard drives for maximum space. The 21.5-inch display delivers crisp visuals and accurate colours, ideal for photo editing, spreadsheets, presentations, and streaming. Whether you're a home user upgrading from an older machine, a student needing a reliable workstation, or a small business looking for desk-saving design, this iMac offers a proven formula in a timeless enclosure.

Configurations to Suit Your Needs

We stock multiple configurations across three cosmetic grades. Grade A units show minimal signs of previous use and are in excellent condition. Grade B units may have light marks or surface wear but remain fully functional and presentable. Grade C units carry more noticeable cosmetic wear—scratches, scuffs, or discolouration—but work perfectly and represent outstanding value. All grades undergo the same testing and carry the same 12-month warranty. Processor choice, storage type, and cosmetic grade combine to offer options from £150 to £250, so you can prioritise speed, capacity, budget, or appearance to match your requirements.

Why Choose Refurbished?

Buying refurbished extends the life of quality electronics, reduces e-waste, and offers substantial savings compared to buying new. This iMac has years of productive use ahead of it, and choosing refurbished means you get a tested, graded, warrantied desktop without the new-product price tag. Every unit ships with a 12-month warranty and a 30-day returns window, giving you the same peace of mind you'd expect from a new purchase. Buyer Area has been supplying refurbished technology since 2011, and every iMac is carefully graded so you know exactly what to expect when it arrives.

Frequently asked questions

What condition will my iMac arrive in?

That depends on the grade you select. Grade A units are in excellent condition with minimal signs of use. Grade B units may have light cosmetic marks or surface wear but remain fully functional. Grade C units show more noticeable wear such as scratches or scuffs, but work perfectly and offer the best value. All grades are tested and carry the same 12-month warranty.

Which processor and storage configuration should I choose?

For general office work, web browsing, and media streaming, the i5 with 1TB HDD offers excellent value. If you work with larger files, run multiple applications simultaneously, or want faster boot times, consider an i7 with SSD or Fusion storage. The 256GB SSD is ideal if you store most files in the cloud; 1TB or 2TB options suit users with large local libraries of photos, videos, or documents.

Can I upgrade the RAM or storage later?

The 2015 21.5-inch iMac has limited user-upgradability—RAM and storage are difficult to access and replace without specialist tools. We recommend choosing a configuration with the RAM and storage you'll need for the foreseeable future. If you're unsure, contact us and we can help match a specification to your use case.

What is your returns policy and warranty coverage?

Every iMac comes with a 30-day returns window from the date of delivery—if you're not satisfied, you can return it for a full refund. All units also carry a 12-month warranty covering hardware faults. If something goes wrong within the warranty period, we'll repair or replace the unit at no cost to you.
