OpenCore Legacy Patcher is a free and open-source software tool designed to enable the installation and operation of modern macOS versions on older Mac computers that are no longer officially supported by Apple Inc.
Following the announcement that Intel Macs will no longer be supported by Apple after macOS Tahoe in 2025, the OpenCore software will no longer be able to provide updates to older Mac computers going forward.[1]
Overview
OCLP is a Python-based project that leverages Acidanthera's OpenCorePkg and Lilu frameworks to create a custom boot environment for unsupported Macs. Unlike traditional methods that modify the macOS system files directly, OCLP applies patches in memory during the boot process, preserving the integrity of the operating system and supporting features like System Integrity Protection (SIP), FileVault 2, and over-the-air (OTA) updates. This non-invasive approach ensures a near-native macOS experience on hardware as old as 2007.
The primary goal of OCLP is to breathe new life into older Macs, enabling features such as AirDrop, Sidecar, Apple Watch Unlock, Night Shift, and Universal Control, which are typically unavailable on unsupported hardware. The project is maintained by a passionate community of developers and hobbyists, with contributions welcomed through its GitHub repository.
