[OS X TeX] XeLaTeX and fontspec issue

[Jeffrey W Roland]

Hi all,

I’m preparing a final book MS and it turns out the publisher only uses four fonts in the series where the book will appear. Of course, none of them are standard LaTeX fonts.  The MS is currently set up for pdfLaTeX and I’m trying to move to XeLaTeX so that I can use Times New Roman as the main font. The problem is that what seems like it should be easy (according to all I’ve read) isn’t working at all for me. Here’s a MWE:

% !TEX TS-program = XeLaTeX

\documentclass{memoir}
\usepackage{fontspec}
\setmainfont{Times New Roman}

\begin{document}
   Hey hey, my my.
\end{document}

When I try to typeset this, I get an undefined control sequence error on '\setmainfont{Times New Roman}’.  Two carriage returns produces an output, but not the right one. (’Times New Roman’ is printed as a line of text.)

I’m using TeXShop 5.57 on a 2025 M4 MB Air running Sequoia 15.7.2 and the current version of MacTeX (installed today, in case that was the problem).

I must be making a silly mistake, but for the life of me I can’t figure out what it is. Thoughts?

TIA,

Jeff
