  • High Quality Macs at unbeatable prices

    Modern personal computers have come a long way from where they were 10 or 20 years ago. But the most recent advances have been in power-efficiency for laptops or installing dedicated machine-learning cores for AI tasks.

    If you're in the market for an office workstation, home all-in-one or something to use for college assignments, 12-core neural network engines or dedicated HVEC transcoders aren't worth the premium.

    Buying refurbished lets you enjoy excellent hardware without paying through the nose. Plus, it means 100% of your purchase uses fully recycled materials!

  • Upgradable and Repairable hardware

    Like the idea of refurbished but worried about how long it will last? It might seem that an older device is closer to the end of its life, but in reality, it can be the opposite!

    Newer devices are built with space-saving and efficiency as maximum priorities. This means that components are now soldered together or integrated completely to the main board.

    In older devices, things like RAM, processors, graphics chips, or even the USB ports, power supply and wireless networking chip can be easily removed, replaced and repaired - and in many cases also upgraded for more power!

    In newer devices, the failure of just one of these parts can spell disaster for the whole device... meaning its much more expensive to repair and much more likely to end up in the landfill.

  • Modern macOS

    Worried that an older computer won't keep up with updates? Not a problem! All of the refurbished Macs we sell can ship with the operating system of your choosing - from versions like OS X 10.13 High Sierra to version 13 Ventura! We can also install the latest Windows 10 for you via the built in Bootcamp feature of Intel Macs.

    How can we do this when Apple might say that newer updates aren't available? Easy - the hardware itself is perfectly capable of running the latest and greatest, just as long as the right kexts (Apple's equivalent to drivers) are installed. OpenCore is how this is possible - see below for more info

Refurbished with OpenCore

Our refurbished Macs run the latest and greatest versions of macOS, even though Apple categorises them as Vintage or Obsolete. This is possible by OpenCore - a lightweight boot-time software package that seamlessly patches the incompatible parts of newer versions so that they can run perfectly on older hardware.

OpenCore is loaded before the operating system boots, and loads custom kernel extensions (kexts), a built-in function of macOS to fix bugs or other issues that would otherwise be present. Once macOS is running, OpenCore is completely silent - the operating system runs just like it would on any other computer!

OpenCore isn't a hack or other unlicened modification to the system - it uses features that are already built in to the system to update parts that would otherwise cause issues with newer operating systems. For example, newer versions of macOS may not include drivers for the audio device in an older Mac. OpenCore can add the kexts necessary (often just found in an older macOS version) so that those features can work properly again.

OpenCore can be updated itself so that it can work its magic on future versions of macOS, when the time comes. Security updates and other essential patches can be installed properly just like on any other Mac, so your refurbished computer can get the full benefit of running up-to-date software. We offer full warranty-based support for our refurbished computers, which includes set-up support and assistance if you need help.
