Notes for macOS
================

Mesa builds on macOS without modifications. However, there are some details to
be aware of.

-  Mesa has a number of build-time dependencies. Most dependencies, including
   Meson itself, are available in `homebrew <https://brew.sh>`__, which has a
   Mesa package for reference. The exception seems to be Mako, a Python module
   used for templating, which you can install as ``pip3 install mako``.
-  macOS is picky about its build-time environment. Type ``brew sh`` before
   building to get the Homebrew dependencies in your path.

Mesa's default builds with the Apple GLX uses Mesa as a front for the
hardware-accelerated system OpenGL framework, to provide hardware acceleration
to X11 applications on macOS running via XQuartz.

Mesa's Gallium drivers can be used on macOS by using the ``-Dgallium-drivers=<drivers>`` build option. Do not use with the previous software rasterizers options, instead add ``llvmpipe`` to the ``<drivers>`` list. Only software renderers and drivers that forward to other APIs can work, any linux hardware drivers will not work. For details on each driver's macOS support see their specific documentation.
