Show HN: Kakehashi – Experimental userspace to run macOS binaries on Linux ARM

Interesting project! A long term vision for MacOS applications is feasible given the success of WINE/Proton with Windows applications.

Are you familiar with the Darling project? https://github.com/darlinghq/darling There's an open PR for ARM64 support https://github.com/darlinghq/darling/pull/1753 Could you combine efforts or do your goals differ too much?

Hi HN, I started developing an experimental project with the goal of running macOS CLI binaries natively on Linux ARM machines. As of now, we have working prototypes for: - 7-Zip: Passes multi-threaded compression tests on an 8k-file tree. Currently ~5.2x slower than native Linux execution, but I already mapped out a clear optimization plan to cut this gap down. - curl: Over 200 commands and options successfully pass our automated Docker test script. - Xcode Tools Git: Basic version control commands (init, add, commit) are up and running, though 100% stability is not yet guaranteed. I would be highly grateful for your constructive criticism, architectural ideas, and feedback! Thank you!

This is something i have been looking for long time, however i have gone through repository and docs and the problem is bigger and solution still seems to be early, I am curious how you gonna take further, will be watching it

If you didn't care about having a fully-redistributable image, but were okay with doing things more like modern old-console-game decompilation projects do (where compiling the project requires the original game ROM as an input), would a project like this be more trivial?

I.e. how hard would it be, comparatively, to design a virtualization framework that doesn't actually ship with any ground-up-rewritten libraries, but instead just expects to execute the binary in question in the context of a full rootfs copied over from a "real" macOS install?

this is something I've been waiting for a long time. I will be watching this with great interest.

If this ever gets far enough I would love to see something similar to yabridge implemented on top of this and be able to run AU binaries on linux.

Would be nice to be able to build iOS apps on Linux ARM runners

AI-written README

Quite the interesting work! Although I don't use macOS binaries, I can see this is promising.

How can we tell that this is truly a clean room project and that there is no code from either (Claude or yourself) that is derived from the Darling project?

Otherwise great project.

I'm curious, how many agent hours have you spent on this so far?
