I went down a deep but entertaining rabbit hole in the other direction for fun: https://github.com/ayourtch-llm/fakelinux - initially with the idea “just replace the syscalls in the executable with some sort of a trap and handle that”.
It almost worked, unfortunately MacOS reserves x18 for platform purposes and Linux doesn’t.
The result is some sort of pretty mad contraption which works sufficiently often to compile aarch64 Linux VPP and its dependencies on the Mac using Linux gcc :)
I suppose with some polish it might be useful for something..
In theory, running Apple Silicon apps on ARM64 linux machines would be really nice. But we are still far from having a performant and feature-complete implementation of doing so.
Darling only targets x86_64 stuff. Still, it's a cool project.
Kinda sad that there are very few updates though [1]
This is the Darling project which aims to run macOS software on Linux for both Intel and ARM64.
But you are probably looking for this:

It is still far away from running your favorite mac GUI apps like Logic Pro or Xcode, but it is a work in progress but can still run command line tools.
What allows Wine to run so many Windows apps that there's not an equivalent for MacOS? Is it lack of interest? Is it a technical thing? I'd even be willing to limit to x86 apps. Or maybe there is and I'm just really out of touch??
While the productivity apps are mentioned in the other comments of this reply, games are another reason. There are far more games on Windows to port and handle than macOS games. And in that case, you got a financial desire in the form of Valve and its Steam store. macOS games tend to be ports from Windows and are usually less featureful.
At a guess: the "killer apps" are things like MS Office and Photoshop, and since they are usually available on both Windows and Mac, there's not such a pressing demand to support similar functionality for Mac apps if the Windows version is easy to obtain.
A lot of work by various companies and people who had various different motivations to work on the compatibility. With CodeWeavers and Valve support, they had a monetary incentive.

I don't think the project kept up with changes to the APIs over the decades compared to how well the Wine project kept up with changes in Windows.
It's also been around since 1993.
