I have followed the above steps but still get this error message. The link says that you have to change the julia path, which I did, but I still get an error message. Does anyone know how I can solve this?

I’m not a mac user, but from the installation instructions on the Julia website here it sounds like you should be running some .app file rather than the .dmg file?

If you have executed the .dmg file and copied the Julia application into the Applications folder, you will find the Julia binary here: /Applications/ . That’s what you want to put in the Juno settings.
