Could you send the contents of the /Users/michaelhendry/.config/fontconfig/fonts.conf file? It's in a hidden folder (.config, which starts with a dot), so you will likely have to toggle something to show hidden files/directories in the Finder. A Google search suggests "Command Shift Dot". After doing that, you should see ".config" in your home folder and find "fontconfig" then "fonts.conf" inside it. Send that file.

LilyPond uses a library called Fontconfig in order to find fonts on the system. Fontconfig supports configuration files. Apparently yours is corrupted, or maybe only valid with a recent version of Fontconfig that LilyPond 2.24 doesn't have. It would be interesting to test the development release 2.25.4, by the way.

Thanks, Jean,

This is what’s in ~.config/fontconfig/fonts.conf:

<?xml version="1.0" encoding="utf-8"?>

<?xml version="1.0"?>

<!DOCTYPE fontconfig SYSTEM "fonts.dtd">

<fontconfig>

 <dir prefix="/System/Library/Fonts"/>

</fontconfig>

The lead-sheets deliver the same “Fontconfig…” error messages, but also include the following warnings:

interpreting music...
warning: cannot find property type-check for `markFormatter' (translation-type?). perhaps a typing error?
warning: skipping assignment

You should always (yes, always) run convert-ly before trying old scores on new versions.

It will automatically fix the syntax of your file to be compatible with the new version of LilyPond.

Developers (like me) put awful amounts of efforts into making it work well. It's a pity not to use that.

In Frescobaldi, that's in Tools > Update with convert-ly.

I’ve tried that on these old files, but it doesn’t resolve the problem.
