This page shows you how to install the CS 1 software on your Mac. You will install a bunch of software. It’s a pain. Come ask a question on Ed Discussion (linked from Canvas) if you run into trouble.
You should be running a recent version of MacOS, preferably 10.13 or higher. You can check which version you are running using “about this mac” menu option the apple symbol menu on the top left of your screen.
Download the file cs1lib.py, unzip it to get the .py file, and put it on your Desktop.
The installation varies somewhat based on your version of the operating system and your computer. Go to this google doc for updated instructions.
