The following document:

\documentclass{report}
\usepackage{fontspec}
\setmainfont{Courier}
\begin{document}
Hello, world!
\end{document}

doesn't compile with the LuaLaTeX format (i.e. with the LuaLaTeX "engine"), and results in the following error message:

ERROR: fontspec error: "font-not-found"

— TeX said —

Here's the Courier listing in my Font Book:

and here's the corresponding font info page:

This post is closely related to this one, however @Moriambar's answer to that post doesn't apply to the present case, and also the error is different (font-not-found here vs. table index is nill there).

Operating System: macOS Sierra Version 10.12.5
MacTex distribution: MacTeX-2017
LuaTeX: Version 1.0.4

The dfont format is not supported in recent versions of luatex, see

https://github.com/lualatex/luaotfload/blob/master/NEWS

  • Remove support for builtin Fontforge libraries (this includes the PFA, PFB, DFONT, and feature file readers).

You may have the Courier also available as truetype or opentype (or if not, I understand that there are font utilities available on the mac to make that conversion, although I do not have a Mac to give details).
