Hi John,

I am using a Mac too, and pdftotext seem to be working, well for an ocr file (see below) if I run pdftotext on the original pdf I get nothing.
cheers,
M

PS I am using brew poppler, which includes pdftotext

If none is found, you get the message you noted. The url dnd works similarly, but there are a bunch of recipes for what to match depending on the base of the url.
