GLSMAC

glsmac is a compact C99 library designed to simplify OpenGL development on macOS by creating a minimal, no-dependency window and OpenGL context setup. It uses only macOS's native APIs (Cocoa and Core OpenGL) without relying on third-party frameworks like GLFW or SDL. This makes it ideal for developers who want tight control over their OpenGL projects, need a lightweight setup for demos or testing, or are writing small graphical utilities without overhead. The code is short, self-contained, and easy to understand, serving as both a useful tool and educational resource.
