To install Dynare for use with MATLAB, execute the automated installer
called ``dynare-4.x.y.pkg`` (where *4.x.y* is the version number), and
follow the instructions. The default installation directory is
``/Applications/Dynare/4.x.y`` (please refer to the `Dynare wiki`_ for
detailed instructions).
After installation, this directory will contain several
sub-directories, among which are ``matlab``, ``mex`` and ``doc``.

Note that several versions of Dynare can coexist (by default in
``/Applications/Dynare``), as long as you correctly adjust your path
settings (see :ref:`words-warning`).
By default, the installer installs a version of GCC (for use with :opt:`use_dll`)
in the installation directory, under the ``.brew`` folder. To do so, it also
installs a version of `Homebrew <https://brew.sh>`__ in the same folder and
Xcode Command Line Tools (this is an Apple product) in a system folder.
All of this requires a bit of time and hard disk space. The amount of time it
takes will depend on your computing power and internet connection. To reduce
the time the Dynare installer takes, you can install Xcode Command Line Tools
yourself (see :ref:`prerequisites-macos`). Dynare, Homebrew, and GCC use
about 600 MB of disk space while the Xcode Command Line Tools require about 400
MB.
If you do not use the :opt:`use_dll` option, you have the choice to forgo the
installation of GCC and hence Dynare will only take about 50 MB of disk space.

Dynare now ships a compilation environment that can be used with the
:opt:`use_dll` option. Specifically, the Dynare installer downloads and
installs the Xcode Command Line Tools, installs `Homebrew <https://brew.sh>`_
under the Dynare installation directory (in the ``.brew`` folder), and finally
installs GCC.

installer ensures that the Xcode Command Line Tools (an Apple product) have
been installed on a system folder. To install the Xcode Command Line Tools
yourself, simply type ``xcode-select --install`` into the Terminal
(``/Applications/Utilities/Terminal.app``) prompt.
