I'm working on my first font and whenever I try to install the OTF I get a "System Validation" error in Font Book. The TTF works fine though. I checked online and asked some people for help, but could not solve this problem. Auto hinting is deselected, so it's not that.
I asked someone else to generate the font and that person got the same problem. It seems to be a Fontlab-related thing on export of OTF.
Does anyone know what this might be and how to fix it?
