About OpenCore-Legacy-Patcher
OpenCore Legacy Patcher is a set of tools and documentation for installing macOS on Macs that Apple no longer supports, limited to the legacy models the project lists. The homepage describes an OpenCore-based approach. Upgrades are applied in memory, and the project states they are never permanent. The site includes guides for creating macOS installers, building and installing OpenCore, post-installation steps, updating, uninstalling, troubleshooting, and some miscellaneous tasks such as restoring Time Machine backups and installing Windows in UEFI mode.
The homepage says the patcher can add support for decade-old graphics cards, Wi-Fi, and Bluetooth chipsets, and can unlock some newer features such as Sidecar, AirPlay to Mac, Night Shift, and Universal Control, including on natively supported models. Updates can be installed from System Settings, with a few more steps than a native update. The homepage does not state which models are supported. Its Supported Models page should be checked before use. The project's documentation lists a current hold on new issues and pull requests.
