+   Even if you're using arm64 (Apple Silicon, M1, M2...) architecture's Mac, the x86_64 version is required.
+   Some modules cannot be installed by conda install or pip install in the arm64 version.
+   Installing the x86_64 version of conda can be done using `rosetta`.
+
+   1. Install Rosetta using the terminal:
+
+        .. code-block:: bash
+
+          /usr/sbin/softwareupdate --install-rosetta --agree-to-license
+
+   2. Open a Terminal Session in Rosetta:
+      - Open your existing Terminal (which is running natively on ARM).
+      - Start a new Terminal session that emulates the x86_64 architecture using the following command:
+
+        .. code-block:: bash
+
+           arch -x86_64 /usr/bin/env bash
+
+   3. Download and install Miniconda:
+
+        .. code-block:: bash
+
+           curl -O https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-x86_64.sh
+
+           bash Miniconda3-latest-MacOSX-x86_64.sh
+
+           /Users/MYUSERNAME/miniconda3/bin/conda init
+
+           conda activate
