Refurbished Apple iMac 21.5" 2015

About this imac

The refurbished Apple iMac 21.5-inch from 2015 delivers a compact all-in-one desktop experience for home offices, students and families. This used iMac combines Apple's signature design with practical performance: a 21.5-inch display, Intel Core processors from the i5-5250U through to the i7-5775R, and a choice of storage from traditional hard drives through to fast SSD options. Running macOS Ventura, it handles web browsing, productivity apps, media streaming and light creative work without the desk clutter of a separate tower. Every refurbished iMac at Buyer Area has been tested and graded, and ships with a 12-month warranty and 30-day returns.

Under the aluminium enclosure you'll find configurations to suit different workloads. The entry-level Intel Core i5-5250U with 8GB RAM and a 1TB hard drive covers everyday tasks – email, Microsoft Office, video calls and web research. Step up to the quad-core i7-4771 or i7-5775R with 16GB of RAM and you gain headroom for multitasking, large spreadsheets and photo editing in apps like iPhoto or Lightroom. Storage spans 1TB HDD, 1TB Fusion Drive (a hybrid of SSD and HDD for faster boot times) and pure SSD options up to 1TB for the quickest file access. The 21.5-inch screen is clear and bright, ideal for documents and streaming, and the integrated speakers, webcam and microphone mean you're ready for Zoom or Teams calls straight out of the box.

Configurations and grades in stock

We currently stock this refurbished Apple iMac 21.5 inch 2015 in fourteen configurations. Processor choices include the Intel Core i5-5250U, i5-5575R, i7-4771 and i7-5775R. Memory options are 8GB or 16GB, and storage runs from 256GB SSD through 1TB HDD, 1TB Fusion Drive and 2TB HDD to 1TB SSD. All units are finished in silver. Condition grades range from C (light cosmetic signs of use, fully functional) through B (good cosmetic condition) to A (excellent cosmetic condition). Every grade carries the same 12-month warranty and has passed the same functional tests, so you can choose the balance of condition and budget that suits you.

Performance for everyday use

The 2015 iMac handles the workloads most households and small offices demand. Web browsing is smooth across multiple tabs, Microsoft 365 and Google Workspace apps run without lag, and streaming video from iPlayer, Netflix or YouTube is crisp on the 21.5-inch display. The i5 models suit general computing – word processing, spreadsheets, email and casual photo management. The i7 configurations with 16GB RAM are noticeably faster when you're editing large image libraries, running virtual meetings while working in several apps, or compiling reports with embedded charts and data. SSD and Fusion Drive models boot macOS Ventura in seconds and launch apps almost instantly; HDD models are slower to start but still perfectly usable once running, and offer more storage capacity for the same price point.

Who this second hand iMac suits

This refurbished iMac UK model fits neatly into home offices where desk space is at a premium: no tower to house, no tangle of cables, just one power lead and an Ethernet cable if you prefer wired networking. Students benefit from the macOS ecosystem – iWork apps are free, and the webcam and microphone are built in for remote lectures and group projects. Families appreciate the simplicity: it's ready to use out of the box, with no separate keyboard, mouse or monitor to source (though you will need to provide your own if the unit does not ship with them – check the configuration). Small businesses running appointment systems, invoicing software or point-of-sale apps on macOS will find the i7 models particularly capable. It's not designed for 4K video editing, intensive 3D rendering or gaming, but for the vast majority of office and home tasks it remains a capable, elegant machine more than a decade after launch.
