I followed the instructions for installing the LatexIt Add-on for Thunderbird, including required packages. Unfortunately, I keep getting this error:


Error message transcript:

LatexIt! run report...

*** Found expression $x(t) = x_0 + v_0 t + \frac{1}{2}at^2$
convert failed with error code 256. Aborting.
Possible explanations include:
- you're running Windows, and you didn't install Ghostscript
- you're running OSX, and you didn't launch Thunderbird from a Terminal

Please see http://github.com/protz/LatexIt/wiki

This message appears even when I launch Thunderbird from the terminal using the command:


just like it says on the wiki. I have the filepaths specified, and Thunderbird can find the files:


The wiki says to use /usr/local/bin instead of /opt/local/bin, but a symlink in that directory gives the same issue. (screenshot was taken with symlink in /usr/local/bin) If I try to use LatexIt when launched from the terminal, I get this output:

This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019) (preloaded format=latex)
 restricted \write18 enabled.

' TeX output 2019.10.12:0040' -> /var/folders/g9/1[omitted_chars]gn/T/tblatex-1.ps

I downloaded/installed all the software (LaTeXIt, MacTeX, ImageMagick, etc. except Thunderbird) 2 days ago, so it should be the most recent versions.

Am I missing anything? I think the problem lies with Thunderbird somehow not believing it’s launched from the terminal, even when it is. I’m fairly sure my path is configured correctly, but it’s possible I’m mistaken. Thanks for the help!
