MercurySS is basically a sub-family (SS stands for Screen Smart)
I’m not using any 3rd party font manager. Have done a ton of work in fonts/typography in the past, and though rusty, have a decent idea of things on my side. I think there’s some issue here, and am keen to be proved incorrect.
I see the .otf font resources in the /resources/fonts/ folder thanks. But the issue persists - I cannot get either the title or the text of a note to bold, UNLESS I change either the font of that selected text or change the Document’s default font.
I even did a quick and dirty and installed the .otf’s in Font Book so I can be assured the system sees the fonts. Sure enough, it does. The fonts can now be used in multiple apps. But still, even in other apps, Mercury doesn’t bold, while Ringside does.
