Guys, I just reacted to sentence "All we can say for certain is that you've had no dual boot success so far", which trs96 corrected later.
This setup used costs more than brand new Mac Mini M1. So it is not about simplicity, comfort and "just works". It is hobby, fun and "because I can". I know all the risks. When doing such tricks, I'm fully aware that next minute whole thing might not work. But I'm engineer. I thrive to clarity and knowledge. Speak with facts and data.
If my triple-boot works well, I do not thank stars and god. I thank people who developed/reverse-engineered this possibility, based on facts on hardware and knowledge of software. It is not coincidence that it works, it works because of steady systematic work. And if it does not, I want to understand why. It is not because "wind changed". No. I do not like foggy stuff. I will find out it sooner or later. And I have found that Hackintosh very well obeys cause and effect. Better than the other famous OS. It is just finding the correlation between cause and effect.
But I still can seek help, right ? This is what this forum is for, correct ? People who well understand risks and fragility of this hack. All which might be over in a fingersnip, when Apple stops support for x64. This whole hackintosh thing is Yugo, not even irony here... we all know that. You can't fault me if I want to install GPS to Yugo. Because you are not better than me. You drive Yugo also.
