I've created a handful of maps using the Iowan Old Style font. After upgrading my Mac to Sierra, it wasn't there any more. I opened Font Book and lo and behold it wasn't there either. After digging around, the font lies in the /Library/Fonts folder and is accessible to applications that must access the folder directly (Adobe products, DYMO Label printer, etc). It isn't however accessible to programs like Pages and QGIS.
I'm trying to figure out how to unhide that font which I've tried a variety of deleting and reinstalling and such. My question would be if anyone knows if there is a way to get QGIS to act like the Adobe programs and access the font folder directly (or however it does it).
I'm currently running QGIS 2.16.3.
