Most of the text in this guide is simply explaining stuff, so don’t let the fact you see a bunch of text scare you off, this really is a simple process. This guide may have steps in it that are not needed for most people, but I include them so that the guide can work for anyone that reads it. This post is the quick and easy guide that should have anyone up and running with OpenCore on the cMac Pros in minutes. I have no experience (yet) with other versions of OpenCore, such as the Legacy patcher, but I fully intend to explore that as well at some point. If you don’t know what OpenCore is, read about some of its benefits here. OpenCore is, for lack of a better word, amazing.
