How to use DIN FF font in LaTeX?

Question

I am trying to use DIN FF font in LaTeX with the fontspec package.

The font is installed in OSX:

In LaTeX I tried:

\usepackage{fontspec}
\setmainfont{DIN}
\setmainfont{DIN FF}
\setmainfont{DIN Regular}
...

Nothing seems to work. With DIN alone it goes in an infinite loop, with the other combinations it simply does not find the font.

Plain LaTeX can't make use of the fontspec package. You need XeLaTeX or LuaLaTeX for that.

If you are already using XeLaTeX (not obvious, but it is in your tags), then you have to make sure that you use the right font name and that the font cache is updated.

For the cache, use fc-cache. To get the list of fonts with their correct names, use fc-list.

If all of that fails, you can resort to using LuaLaTeX or telling XeLaTeX what you want exactly:

\documentclass[a4paper]{standalone}

\usepackage{fontspec}
\setmainfont[path=/my/dir/fonts]{DINFF.ttf}
