In this video, I go over the process of completely restoring an A12Z-based Apple Silicon Developer Transition Kit "DTK" Mac Mini that I got from China sold essentially as scrap. After many months of work, research, and testing, I was FINALLY able to fully restore one of these salvage DTK logic boards, and get it back up and running booting macOS! The culmination of all that work is shown here, as well as the process of making it into a complete DTK machine using a 2018 Mac Mini chassis and parts.
