Gustavo, thank you a lot! It works!

I created an alias for the terminal, which shortens the output a little bit. I'm not a master of the grep instructions so I wasn't able to get rid of the date. But I hope it will help you: alias robofontOutput="tail -f -n 100 ~/Library/Application\ Support/RoboFont/robofont-3-py3.log | sed 's/> OUTPUT > ROBOFONT >>/>>>/; s/ >>/>>/'" Cheers

The file in your bin folder is a symbolic link to a file inside the app bundle. If you remove the app the symbolic link will not work anymore...

well spaces in a folder are never a good idea :)
