Summary
Steamac is an open-source project that runs Valve's official ARM64 SteamOS image in a lightweight virtual machine on macOS 15 and later on Apple Silicon, using Apple's Hypervisor.framework through libkrun. Graphics go from the guest's Vulkan stack via Venus to MoltenVK or the experimental KosmicKrisp driver, then to Metal.
