Howdy,

Works fine here.

How are you trying to typeset this. You need to use either xelatex (or xelatexmk) or lualatex (or lualatexmk).

If you use lualatex(mk) it should work out of the box.

If you use xelatex(mk) and call the font by name (as your example does) Font Book needs to `know' about it since xelatex uses the OS font system to find the font file. To do that you can either copy that font, it's in /usr/local/texlive/2025/texmf-dist/fonts/opentype/public/qualitype/QTLinostroke.otf, to your personal font folder, ~/Library/Fonts or create a Library in Font Book and install fonts from /usr/local/texlive/2025/texmf-dist/fonts/opentype or sub-folder thereof.

Good Luck,
