1. What is Patched Sur? Patched Sur is a community-developed, open-source graphical patcher tool designed to allow unsupported Macs (typically pre-2013 models) to run macOS Big Sur (and later, versions like Monterey and Ventura via its successor projects).
Only use Patched Sur if you have a specific need for Big Sur (e.g., legacy software compatibility) and are willing to accept its flaws. For almost everyone else, use OpenCore Legacy Patcher for a more robust, up-to-date experience. This content was accurate as of 2025. Always check the official GitHub repositories for the latest status of any patcher tool. patched sur
