@section compat_osx OpenGL on macOS
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.

[GL_KHR_no_error](https://www.opengl.org/registry/specs/KHR/no_error.txt)
extension.
@note This hint is experimental in its current state. There are currently
(October 2015) no corresponding WGL or GLX extensions. That makes this hint
a [hard constraint](@ref window_hints_hard) for those backends, as creation will
fail if unsupported context flags are requested. Once the extensions are
available, they will be required and creation of `GL_KHR_no_error` contexts may
fail on early drivers where this flag is supported without those extensions
being listed.
