Required Dependencies
---------------------
Installing Manim
----------------

To install all required dependencies for installing Manim (namely: Python,
and some required Python packages), run:
As of July/2024, brew can install Manim including all required dependencies.
To install Manim:

.. code-block:: bash

brew install py3cairo

On *Apple Silicon* based machines (i.e., devices with the M1 chip or similar; if
you are unsure which processor you have check by opening the Apple menu, select
*About This Mac* and check the entry next to *Chip*), some additional dependencies
are required, namely:

.. code-block:: bash

brew install pango pkg-config scipy

After all required dependencies are installed, simply run:

.. code-block:: bash

pip3 install manim

to install Manim.

.. note::

A frequent source for installation problems is if ``pip3``
does not point to the correct Python installation on your system.
To check this, run ``pip3 -V``: for macOS Intel, the path should
start with ``/usr/local``, and for Apple Silicon with
``/opt/homebrew``. If this is not the case, you either forgot
to modify your shell profile (``.zprofile``) during the installation
of Homebrew, or did not reload your shell (e.g., by opening a new
terminal) after doing so. It is also possible that some other
software (like Pycharm) changed the ``PATH`` variable – to fix this,
make sure that the Homebrew-related lines in your ``.zprofile`` are
at the very end of the file.
brew install manim
