    General guidance from repository metadata, not legal advice. How we score

    From the README

    A Python-based project revolving around Acidanthera's OpenCorePkg and Lilu for both running and unlocking features in macOS on supported and unsupported Macs.

    Our project's main goal is to breathe new life into Macs no longer supported by Apple, allowing for the installation and usage of macOS Big Sur and newer on machines as old as 2007.

    Noteworthy features of OpenCore Legacy Patcher:

    Note: Only clean-installs and upgrades are supported. macOS Big Sur installs already patched with other patchers, such as Patched Sur or bigmac, cannot be used due to broken file integrity with APFS snapshots and SIP.

    Note 2: Currently, OpenCore Legacy Patcher officially supports patching to run macOS Big Sur through Sonoma installs. For older OSes, OpenCore may function; however, support is currently not provided from Dortania.
