Everyone gets to name their projects for their own reasons. If the pitch is basically an “alternate apple” macOS, I would have chosen one of the other other (alternate) apple varieties as the root of my OS. Missed opportunity I guess.
There used to be a bootable Darwin instance that Apple published, which on paper would've made things a bit easier, but they stopped publishing it a while ago. It never resulted in any serious OS with a UI however.
By referencing the 90s it is a reminder that Mac started on an entirely closed source kernel. It's a regression towards the Mac mean more than a regression away from it.
The Mac GUI is closed source. You're not cloning it without being sued by Apple's turbo lawyers or at the very least receive a C&D. This is for console applications?
macOS will now be ARM-only. If you buy Apple hardware you already have a license for the real thing.
Why run a TBD meme OS when you could run Darwin, FreeBSD, Linux, etc. or real macOS to accomplish whatever unclear goals are presented here?
*sigh* This is for no one, there is no viable use case. The ReactOS team will be sending a fruit basket.
That's what this is. Darwin isn't installable today. Apple just dumps a bunch of source code. Previous attempts at making Darwin bootable didn't go far and had no GUI.
why do anything? why Linux? why FreeBSD? why Mac at all? Why build your own wind turbine when corporations make large ones? Why build a cyclekart when you own a car? Why workout when everyone's going to die?
With that mindset, everything is useless and nothing has a point. Have I made my point?
I regret to actually say this, and mean no controversy - but, I have been actually asking myself just that - and, not in the "workout or not" sense, alone. In the "does anything have a point", way. Apologies.-

In general, things have meaning because people assign meanings to them. Nothing inherently has meaning as meaning exists only within the human mind/soul. If you are searching for meaning, you will find nothing.
"This is a huge effort. Y'all must be crazy!
Yes. Here's to the crazy ones... because the people who are crazy enough to think they can change the world are the ones that do.
In all seriousness, though, it's not my first rodeo. I have no illusions about the scale of building an OS or how long projects like Haiku, ReactOS or GNUStep took to get usable. This is just something I like doing in my Copious Spare Time™ and that I hope will be useful someday.
I've always liked Apple's design and elegance, but am not thrilled with the direction of recent macOS® or how closed the hardware has become. And I'm a big believer in open source. So ... let's build something that feels as elegant, without all the lock-in, and maybe (just maybe) I can get it to a point that reasonably useful Mac apps build & run on it. And if not, we'll build a lot of cool pieces along the way and learn a ton. I'm OK with that."

Good luck! There are many attempts at doing something similar. We can't really see anything to judge it by, yet.

>but we're not a fan of the ever-closing hardware and ecosystem
What has changed about Apple's ecosystem vis a vis openness, hardware, or the 'ecosystem'?
The macOS ecosystem is pretty much the same as it has been since 1997
a lot of the kernel extensions are closed source proprietary. The core is still open but a lot of what makes modern Mac, Mac, are those kexts.
how has that changed over the past 20 years? the proprietary parts of Mac OS X and now macOS have been proprietary from the beginning

Would be nice to have a screenshot in the overview page
What, exactly, is the point of this?
The Mac GUI is closed source. You're not cloning it without being sued by Apple's turbo lawyers or at the very least receive a C&D. This is for console applications?
macOS will now be ARM-only. If you buy Apple hardware you already have a license for the real thing.

I dunno you could definitely do a "wine but for macos" kind of implementation, e.g., https://www.darlinghq.org/ without breaking IP laws
I've always been shocked by the lengths of time people will commit to proving wrong the folks who tell them "you can't do that."
