I have an old MB Pro running Monterey 12.7.6 (I’m aware that it’s out of support) and I’ve found that Things 3 doesn’t support Markdown on this laptop. I’m also aware that the Things 3 Markdown implementation has its issues. However I also have an iMac running Ventura 13.7.6 and on this, Things 3 renders Markdown just as I’d expect. I had wondered if it was a Perl dependency as the Markdown specification page defines one, but I’ve checked and they both have the same (later) version. Does anyone know if it’s possible to get Things 3 rendering Markdown correctly on Monterey?
