You may already notice that information provided by a system library on modern macOS versions mentions Metal, so that it is already a wrapper over other graphics API (although Apple may cheat by accessing some internals).

Unfortunately, it has stuck on OpenGL 4.1, and there is no reason to expect the version will ever grow up the library could be even removed in some newer macOS.
#INSTALLING OPENGL 4.4 ON MAC DRIVERS#
In contrast, macOS is much more closed system, where all graphic drivers are part of the system and cannot be (normally) updated without updating system itself. Graphics card vendors provide drivers independently from Microsoft and OpenGL capabilities can be implemented without Microsoft approval.
#INSTALLING OPENGL 4.4 ON MAC DRIVER#
On Windows, system-provided opengl32.dll doesn't actually implement OpenGL but is rather a proxy-library dynamically loading functions from a driver provided by a graphics card vendor.

Built-in OpenGL on macOS works a little bit different from other platforms like Windows or Linux.
