MGL is a C++ library that implements OpenGL 4.6 and OpenGL ES 3.x on top of Apple's Metal API, mapping OpenGL state and draw calls to Metal render pipelines. It includes a modified GLFW build so existing OpenGL applications can run on macOS with Metal-backed contexts.

Use cases

• run OpenGL 4.6 applications on macOS via Metal
• port legacy OpenGL code to Apple Silicon Macs
• use OpenGL contexts with GLFW on modern macOS
• develop OpenGL games or tools on MacOS platform
• translate OpenGL shaders and draw calls to Metal

When to choose

• you need OpenGL 4.6 or ES 3.x functionality on macOS where Apple deprecated GL
• you want a lightweight translation layer rather than a full emulator like MoltenVK-for-GL alternatives
• your app uses GLFW and you want Metal-backed contexts with minimal changes

When to avoid

• you need full OpenGL conformance or every extension, since coverage is partial and tests are functional rather than exhaustive
• you target platforms other than macOS
• you need guaranteed production stability for mission-critical software
