I don't think scanning directly into the program from your scanner works on Mac OS. I'm also on Mac OS and OpenToonz does not "see" my Brother Scanner ... I also have
SANE (Twain) installed and it doesn't access SANE , either.
The workaround is to scan all the drawings , save to a folder , then import the scans into an X-sheet layer. (drag and drop of the scans also works) But too bad the special Ghibli GTS scanning interface does not work for Mac . Who can complain ? It's free . So we have to deal with it. Maybe someone will develop a plug-in that will allow direct scanning on Mac.
