Different Resources used in my Blog for Learning Operating Systems
- Operating System in 3 Easy Pieces by University of Wisconsin Madison, they have a good Operating Systems course.
- MIT is another good resource for Operating Systems

Lastly my Alma mater Michigan State University (Go Green!) CSE 325 Class is another good resource for Notes and Code for learning Operating Systems
Setting things up for the Operating System
- I’ll be using the XV6 Operating System from MIT to learn
Steps to download/install XV6 on macos
- Clone XV6
git clone https://github.com/mit-pdos/xv6-public
- Run/Compile OS using make then make qemu-nox
make
make qemu-nox
Note on Compling:
For some reason I had to open *usertests.c** file and “/” out *lastaddr = 99; for the program to compile.
Good Video Showing how to Compile XV6 on Mac
How to Exit out of OS
- control + a
