I'd really like to be able to use Futura in a project using QuarkXpress 4.1 (I have no option to use another app in this case) under Classic in Panther. I have X11 Suitcase available to activate the font, but the .dfont that comes with OS X doesn't appear compatible, as well as another OT version I have. What version of Futura would I need to use it like I want?
