# Using MathTime 2 Lite with MacTeX on Big Sur

I have Big Sur and am using MacTeX. I'm trying to use the MathTime 2 Lite fonts.

I downloaded the package from CTAN and followed the instructions here, but doesn't work. I also tried the installer but apparently I don't have the neccessary files. (I can't download it from the official downloads page from PCTeX, as the server doesn't respond to my request and I can't access the website.)

What should I do? (And by the way, I can't use other Times math fonts, as I'm fond of MathTime's individually designed large operators.)

## Steps to reproduce

1. Install the package from CTAN and place the texmf folder in /Users/[username]/Library/.
2. Create a .tex file with this code:
\documentclass{article}
\usepackage[lite]{mtpro2}
\usepackage{mathtools}
\begin{document}
$\sqrt{\sum_{i=1}^n (y^i -x^i )^2 } \quad \text{vs.}\quad \SQRT{\sum_{i=1}^n (y^i -x^i )^2 }$
\end{document}

• Thanks! My distribution is TeX Live and I updated it about 6 months ago. My TeX engine is pdfLaTeX. Jun 13 at 9:26
• Please try updating your TeX distribution to MacTeX2021 and updating all LaTeX packages (via sudo tlmgr upate --self --all from a command window) before you go any further. Please advise when you've finished that step and whether you've encountered any warning or error messages.

• I will do that, but just curious, why MacTeX? Is there a difference with TeX Live? Jun 13 at 10:00
• MacTeX is TeXLive plus a few MacOS-specific goodies.

• What, exactly, did you do that didn't work? Jun 13 at 20:30

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}


works.
