I solved it in the same way in this issues

macOS Big Sur, could not load OpenGL library #61

vi /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/OpenGL/platform/ctypesloader.py

def _loadLibraryWindows(dllType, name, mode):
    """Load a given library for Windows systems

    returns the ctypes C-module object
    """
    fullName = None
    try:
        fullName = util.find_library( name )

        # Insert this codes
        fullName = '/System/Library/Frameworks/OpenGL.framework/OpenGL'
        #

        if fullName is not None:
            name = fullName
        elif os.path.isfile( os.path.join( DLL_DIRECTORY, name + '.dll' )):
            name = os.path.join( DLL_DIRECTORY, name + '.dll' )
    except Exception as err:
        _log.info( '''Failed on util.find_library( %r ): %s''', name, err )
        # Should the call fail, we just try to load the base filename...
        pass
    try:
        return dllType( name, mode )
    except Exception as err:
        err.args += (name,fullName)
        raise

However, there are still font related issues.

Unable to load font: GLUT_STROKE_ROMAN
Unable to load font: GLUT_STROKE_MONO_ROMAN
Unable to load font: GLUT_BITMAP_9_BY_15
Unable to load font: GLUT_BITMAP_8_BY_13
Unable to load font: GLUT_BITMAP_TIMES_ROMAN_10
Unable to load font: GLUT_BITMAP_TIMES_ROMAN_24
Unable to load font: GLUT_BITMAP_HELVETICA_10
Unable to load font: GLUT_BITMAP_HELVETICA_12
Unable to load font: GLUT_BITMAP_HELVETICA_18

Is there no way?

This is all fixed in Python3.10

Specifically it was fixed in Python 3.9.1 and 3.8.10.
