Kakehashi Enables Running macOS ARM64 Binaries on Linux ARM64
Key points
- Kakehashi translates macOS ARM64 binaries to run on Linux aarch64.
- It operates as a userspace translation layer, not using JIT.
- Supports running CLI tools like 7-Zip and curl.
- Verified on Docker/Colima and UTM for Linux aarch64.
Introduction to Kakehashi
Kakehashi is an experimental userspace translation layer designed to enable the execution of macOS ARM64 (Darwin Mach-O) binaries on Linux aarch64 systems. This project focuses on a command-line interface (CLI-first) approach and does not utilize Just-In-Time (JIT) compilation for its translation process.
Technical Functionality
The system works by loading Darwin Mach-O binaries on Linux aarch64, mapping a freestanding libSystem, and translating BSD syscalls. This allows real guest applications, such as clang probes, 7-Zip (7zz), and curl, to run. It has been verified to function within Docker/Colima and UTM environments on Linux aarch64.
Installation and Usage
Users can install Kakehashi via `cargo install kakehashi` or by building from a checkout. Once installed, commands like `kh bottle ensure` and `kh install 7zip` can be used to set up and install macOS binaries. The `kh run` command executes the translated binaries, with examples provided for 7-Zip operations like archiving, testing, and extracting, as well as curl commands for HTTP/HTTPS requests.
File System and Docker Integration
Kakehashi handles file paths by resolving relative output and archive paths against the host's current working directory. It also bridges `/Volumes/linux/` within the bottle to the host's root directory. Docker helper scripts are available to facilitate running and testing applications like 7-Zip and curl within Docker containers, with artifacts output to a specified host directory.
