@section compat_osx OpenGL 3.2 and later on OS X
Support for OpenGL 3.0 and above was introduced with OS X 10.7, and even then
only forward-compatible OpenGL 3.2 core profile contexts are supported. There
is also still no mechanism for requesting debug contexts. Versions of OS
X earlier than 10.7 support at most OpenGL version 2.1.
Support for OpenGL 3.2 and above was introduced with OS X 10.7 and even then
only forward-compatible, core profile contexts are supported. Support for
OpenGL 4.1 was introduced with OS X 10.9, also limited to forward-compatible,
core profile contexts. There is also still no mechanism for requesting debug
contexts. Versions of Mac OS X earlier than 10.7 support at most OpenGL
version 2.1.
Because of this, on OS X 10.7, the `GLFW_CONTEXT_VERSION_MAJOR` and
`GLFW_CONTEXT_VERSION_MINOR` hints will fail if given a version above 3.2, the
`GLFW_OPENGL_FORWARD_COMPAT` is required for creating OpenGL 3.2 contexts, the
`GLFW_OPENGL_DEBUG_CONTEXT` hint is ignored and setting the
`GLFW_OPENGL_PROFILE` hint to anything except `GLFW_OPENGL_CORE_PROFILE` will
cause @ref glfwCreateWindow to fail.
Because of this, on OS X 10.7 and later, the `GLFW_CONTEXT_VERSION_MAJOR` and

`GLFW_OPENGL_CORE_PROFILE` will cause @ref glfwCreateWindow to fail.
Also, on Mac OS X 10.6 and below, the `GLFW_CONTEXT_VERSION_MAJOR` and
`GLFW_CONTEXT_VERSION_MINOR` hints will fail if given a version above 2.1, the
