That's just the architecture and driver independent part of the kernel. The kernel source tree is 15M lines or so.

I’d love to know what the smallest OS is that can boot on an old MacBook, get to network (wired or wireless), and includes a basic browser (tui or gui) even if it doesn’t drive all the onboard hardware. That feels like it would be an excellent learning platform.

Not vouching for it working on a MacBook, and it sure ain't "modern", but you might love poking around in QNX. 1.44 MB was plenty for everything.

These days, most people would run it in qemu, e.g. https://www.youtube.com/watch?v=xqILeQ-Cg-A

thanks - in that vein there's also freeDOS. but I assume if someone had built a learning OS they could make it much smaller?

haven't tried:
