Installation steps (what did you do to get it all going?)

For Mac Os Mojave is just plug and play, you can use it with internal or external monitor or both just great
For window 10, i spent 1 week to finally make it work. the problem is with the error 12. and after following Mikael's guide the error 12 is gone. it works with external ssd windows 10  boot. for now i can only use external monitor for windows 10.
