No earlier mention of .ttc as far as I can tell in this thread, Stephen. Anyhow, as a non-user of Apple products, I simply downloaded those version that were easily found online. In practice these turned out to be in .ttf and .otf formats.I think you must be looking at either .otf, or updated .ttf fonts (if there is such a thing). The issue under discussion here (as I understand it) is *Apple’s* distribution of .ttc (truetype collection) fonts.
