GitHub released Klepton, a JIT-less relinker and compatibility layer enabling Android ARM64 VR APKs to run on Apple Vision Pro and macOS. The tool translates Android .so libraries into loadable Apple .dylib and .framework libraries, linking them into the Klepton runtime. Klepton currently supports Java-thin applications, translating GLES 3.2 to ANGLE GLES 3.0 with a Metal backend and Vulkan to Molten VK.

The frontend platform and OS-specific services include Molten VK, ANGLE, Compositor Services, ARKit, and Game Controller. While Android and macOS reserve x18, some older Android apps still use it, and macOS zeros x18 on context switches. Klepton patches all x18 usage to use per-library TLS slots instead.
