 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.
