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 software rasterizers also work on macOS. To build, set the build options
``-Dosmesa=true -Dglx=xlib``.
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 ``swrast`` 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.
