Could you build this?

No An experimental userspace compatibility layer to execute Mach-O Darwin binaries on Linux ARM involves reverse engineering XNU syscalls, libSystem, and Mach message passing.

What it would actually take: This requires building a custom dynamic loader/linker for Mach-O binaries, an emulation/translation layer for XNU kernel system calls (mach traps, BSD syscalls), and mapping POSIX/Darwin threading models onto Linux. The hard parts include handling Darwin-specific IPC (Mach ports), thread-local storage differences, and dynamic runtime bindings (dyld). This demands elite operating systems expertise, ABI translation, and kernel-level reverse engineering.

Discussion

20 comments analyzed.

Competitors mentioned: Darling, QEMU, osxcross, Wine, LibreOffice Calc (vs Excel)

Concerns raised: Market size - too few macOS programs people want to run on Linux, Project momentum compared to similar efforts like Darling, Maintenance burden with each macOS update, Copyright infringement concerns with code transformation, Complexity of supporting macOS-specific internal APIs

Feature requests: Cross-compilation from x86_64-linux to darwin, GUI support for music production (Logic Pro plugins), Binary sanity check tool, Asahi Linux compatibility testing, Runtime testing capability for Apple compilation
