The application is currently available for Windows, macOS and Linux. They are self-contained and do not need to be installed.
Make sure to read the quick tour and browse through the reference guide. Also download some classic books to help you get the hang of Logo!
They auto-update and we will periodically push fixes to production (the end-user update channel).
Windows will probably complain the application is unsigned the first time you open it.
You will need to do the right-click-and-Open thing on macOS the first time you open it because I didn’t sign the app (yet).
To run turtleSpaces in Linux you will need to make sure you’ve installed PortAudio https://reposcope.com/package/libportaudio2 (try to run it first and see if it complains before installing PortAudio).
