FontForge http://fontforge.github.io is a font-editing app which I need to open font files in my Documents folder. Probably because of the X11 origin of FontForge, attempting to navigate to the Documents folder in its file opening dialog does not trigger the usual Catalina warning '"FontForge" would like to access files in your Documents folder' with its Don't Allow/OK buttons. The only thing the file opening dialog shows is
Operation not permitted
I went to System Prefs > Security & Privacy > Privacy > Files and Folders, clicked the lock icon at the bottom left and authenticated, to no effect: the +/- buttons at the bottom of the list of apps that requested access remain greyed out.
Is there a way to circumvent this, or a command-line utility allowing (once sudo'ed) to manage app access to files and folders?
