Darling is a translation layer that enables the native execution of unmodified macOS binaries on Linux systems. It functions as a compatibility environment that maps macOS-specific system calls and environment variables to the host Linux kernel, allowing desktop applications to run without the need for full hardware virtualization or emulation.
The project achieves this by implementing a user-space kernel emulation environment that intercepts and translates kernel traps into their Linux equivalents. It includes a custom loader for binary files that resolves dependencies against open-source implementations of Apple system frameworks, while managing the translation of thread-specific memory structures and inter-process communication mechanisms required by macOS applications.
This environment bridges the gap between operating systems by providing the necessary infrastructure to execute proprietary software designed for Apple hardware directly on Linux distributions. The project is distributed as source code intended for compilation on Linux systems.
