 Apple macOS
 ===========
 
-Apple's macOS is fully supported. You need to download and install a recent
-version of the Apple developer application Xcode. Xocde is available in the App
-Store. Make sure you install the Command Line Tools add on available for
-download within Xcode and once installed open a Terminal shell and enter the
-command ``cc`` and accept the license agreement.

+Homebrew and Macports should work but are not tested by the project as

+problems there may be. We recommend reaching out to those projects for

+Python
+~~~~~~
+
+Building GDB requires the installation of Python's development
+libraries. Building GDB includes the Python runtime header
+``Python.h`` and linking to the Python runtime libraries. The RSB
+detects a valid header and libraries before starting a GDB
+build.
+
+It is recommended you run the RSB in a Python virtual environment. A
+virtual environment manages paths for you, provides a ``python``
+executable mapped to the version the virtual environment is built with
+and a command to find the appropiate runtime header and library files
+GDB needs. Virtual environments make it easier to update Python to a
+newer version if this is needed.
+
+Apple has removed support for Python's development libraries from
+recent versions of MacOS as users can manage Python using the
+installer packages provided by the Python project.
+
+To install:
+
+#. Download a Python installer for MacOS from https://www.python.org/.
+
+#. Run the installer and install Python.
+
+#. Open a terminal and update your shell profile using the command
+   Python provides. For Python 3.12 the command is:
+
+   .. code-block:: shell
+
+      /Applications/Python\ 3.12/Update\ Shell\ Profile.command
+
+   Check with:
+
+   .. code-block:: shell
+
+      % type python3.12
+      python3.12 is /Library/Frameworks/Python.framework/Versions/3.12/bin/python3.12
+
+#. Create a virtual environment:
+
+   .. code-block:: shell
+
+      mkdir $HOME/development/rtems
+      cd $HOME/development/rtems
+      python3.12 -m venv py3.12
+
+   Activate the virtual environment:
+
+   .. code-block:: shell
+
+      . $HOME/development/rtems/py3.12/bin/activate
+
+   You are now ready to the build the tools within the virtual
+   environment.
