Installing Emscripten on the Mac is not always straightforward. There are common problems mostly related to SSL certificates. If you encounter any of these, first search the internet for help as someone else will usually have encountered the same issue. If you cannot find a solution, you will need to raise a support ticket at https://github.com/emscripten-core/emscripten/issues/.
To install Emscripten on the Mac, first start a terminal window (Applications/Utilites/Terminal).
You should see a MacOS terminal window. First, make sure both GIT and Python are installed properly. To do this, type "git --version" and "pyhon --version" in the command prompt window, you should see some output as in the diagram below.
If you have both GIT and Python installed, you can now move onto the next step. Vensim has a script that will download and install the Emscripten SDK for you. In the terminal window, change folder to /Users/Shared/Vensim/comp/wasm. Now make sure the script is "executable" but typing the command "chmod 755 install_emscripten_sdk_macos.unx".
Now we are ready to run the script. Do this by issuing the command "./install_emscripten_sdk_macos.unx" in the terminal window. This will download the Emscripten SDK for you. If it works, you should see the following in the terminal window.
