My C programming class in 7th grade had me doing something a lot like the second half of this for our final group project. We just had a pointer to the start of video memory and a few very basic support structures like that, and the rest was up to us. I ended up writing most of the core layer, while the rest of the team implemented game features and made sprites and all that other stuff. I walked out of that class really knowing what programming was about, even if it took me a few more years to get a practical coding environment going for myself. Looking back, that teacher was one of the best I've ever had, in any subject. He was a huge follower of the socratic method, never handing us answers, but getting us to come up with them ourselves, or find them in documentation, while never letting us get mired in a dead end.

I think he just has a lot of free time on his hands. You see it's not overly difficult to develop an os, it's mainly very time consuming and it's easy to write bugs. The theory is rather easy.

you will need some knowledge of computer architecture, core concepts of operating systems and some skill in assembly. A few books that can help you with that: - Programming From The Ground Up by Jonathan Bartlett: teaches you x86 assembly, a bit of computer architecture and other things - Operating System Concepts by Avi Silberschatz, Greg Gagne, and Peter Baer Galvin: it's a great introduction to operating systems, it teaches you how the operating system interfaces with hardware, how the operating system gives support to the user space programs etc. It will teach you much more than it's needed to built what's on the video tho. - manuals on the hardware you're trying to write software to - for writing drivers there are a lot of books about drivers on linux, they might give you a good idea how to do it

Back in the PowerPC days, running anything besides Mac OS is complicated. Now with Intel, it's way easier if you want to run a recent Windows version with Boot Camp. Anything besides that might become challenging, too. But soon, with Apple Silicon, I think it'll be straight impossible to run anything else than macOS.
