OpenCore Legacy Patcher is a free, open-source tool that lets you install and run newer versions of macOS on older Mac hardware that Apple no longer officially supports. Think of it as a way to breathe new life into your aging MacBook, iMac, or Mac Pro.

The computer I'm doing the walkthrough on is a mid-2014 iMac.

IMPORTANT!!
PLEASE MAKE SURE YOU HAVE BACKED UP YOUR DATA IF YOU DECIDE TO ATTEMPT THE PROCESS.
