Nope the default way is not to store anything in Documents, thats a folder completely controlled by the user the Default way to shared data between applications which is what pharo images are is exactly where PharoLauncher Stores its Images in MacOS.��
The folder is invisible because it is... well ... invisible, you can use this instruction to reveal your hidden folders
I definitely do not want for any App to pollute my Documents folder, Doc folder is for me and me alone.��
I tried to port PharoLauncher to the terminal but I failed miserably understanding the code, but no creating arguments for the command line is not hard at all.��
