harvey VS PureDarwin

NIX has zero-copy stuff that I don't know anything about.

> Starting with a stripped-out Linux kernel and a standard toolchain (whether gcc or clang)

HarveyOS[1] is a Plan-9 inspired OS but with a modern toolchain using C11 and Go. Not much activity in the last few years, but then a burst of activity this summer.

Here is Harvey's license today, https://github.com/Harvey-OS/harvey/blob/main/LICENSE. "Copyright 2021 Plan 9 Foundation."

You can do this with Harvey OS. It uses gcc or llvm to build the entire system.

Every Christmas break I always hope I'll have the emotional energy to dig back into https://github.com/PureDarwin/PureDarwin#readme and see if I can get it to boot, even on VirtualBox, let alone some hackintosh friendly hardware like OP did

I am super, super cognizant that the devil's in the proverbial details, but they sure do seem to publish a lot of macOS into the open <https://github.com/apple-oss-distributions/distribution-macO...> so my interest is to map out the parts that are missing

I'm also aware that Darling exists (e.g. https://news.ycombinator.com/item?id=38423469 ) but if it's anything like Wine -- no, thank you. The only reason Wine (and their CrossOver friends) are required to exist is because there's no suitable open source release of Windows, so emulating the bugs is glucose cheaper. I had high hopes for ReactOS when I was in college, but I think they're just pushing that rock uphill (although I am super glad the project exists)

Having said all of that, don't overlook that even if I snapped my fingers and had a PureDarwin built 14.3 .iso this very second, the supply chain for x86_64 applications for any such OS is likely going the way of the dodo, since it won't be in a vendor's best interest to dedicate resources to building releases for what they assume is a dead platform

Neat project. Only two commits for 2022 though: https://github.com/PureDarwin/PureDarwin/commits/main

Either a parody, or a new Linux distribution project like PureDarwin, I guess.

However, you're again mistaken about Apple's own open source code. Most of their open source code is in relation to Unix/BSD stuff they've used in their operating systems, such as the Mach kernel and some (low-level, from my understanding) parts of FreeBSD. Over the years, they've slowly been adding their own proprietary code, and you'll find that even their open source macOS "base", Darwin, is far from complete (go have a look at the PureDarwin project to see more or less what can be made from the macOS code Apple has made publicly available).
