I’m always confused by people who don’t seem to understand that MacBooks and iPhones run different OSs. Why would they run the same OS?

You can install pretty much anything on a MacBook via the open-source package manager brew. I’ve been exclusively using Linux at home for almost 20 years, but on my work computer, which is a MacBook, I really don’t find much is missing. I use the same oh-my-zsh profile on both, brew install the real version of most utilities, and I move on with my life and get work done.

Apple doesn’t lock down the bootloader at all, so it’s trivial to install Asahi Linux now if you want to. I did this on my home computer because I like the screen, battery life, and keyboard layout.
