This iMac has been professionally upgraded and tuned for modern use. It has been fitted with a 500GB SSD and 12GB of RAM, making it significantly faster and more responsive than the original factory configuration. Boot times, app launches, and general navigation are all smooth and quick — a huge improvement over the original hard drive setup.

It is running macOS Ventura via OpenCore Legacy Patcher (OCLP), allowing full access to modern macOS features including iCloud, Apple ID, App Store, and current applications. Everything is fully functional and ready to use out of the box.

⚠️ IMPORTANT – READ BEFORE BUYING:

This system is running a patched version of macOS using OCLP. It is stable and working well, but:

• DO NOT factory reset or wipe the system unless you understand how to reinstall macOS using OCLP and apply post-install root patches.

• If you do reset it without proper knowledge, you may lose functionality and will need to manually reconfigure the system.

Additional Setup & Features:

• Comes with a clean Admin account

• Includes Macs Fan Control (MFC) pre-installed

• A hardware inline thermal sensor has been installed, meaning:

  • Fans behave normally with the SSD

  • No constant max fan noise like typical iMac SSD upgrades

  • MFC can be removed if desired — system will still function class="p4">

    Condition:

    
    

    The iMac is in good overall condition for its age. The display is clean with a very minor, faint pressure mark near the top-left corner, which is imperceptible during normal use and only slightly visible on bright white backgrounds.

    
    

    All ports, Wi-Fi, audio, and system functions are working properly.

    Support:

    
    

    This machine has been upgraded by a CompTIA A+ certified repair technician and Apple Developer.
