In this video, I'll explain how to install macOS Sonoma on older, unsupported, Apple Mac models. This could be a fresh install, upgrade or dual boot. We will do this using the OpenCore Legacy Patcher. For this video, I'll be using an Mac Mini Late 2014 but this method should work for Mac Mini, Mac Pro, MacBook Air or Pro and different models of iMacs as well.

All the steps I go through and commands or links I'm using in the video can be found in detail on my blog as well: https://jensd.be/1998/apple/installm...
