BTW, do you know other (freely-available [and preferably offline])

I actually wasn’t aware that there’s a Mac version of Okular.
there's also a windows version, quite ok
(But annotations are still a PITA.)
maybe they don't care to much about that, most pushed-in-git changes are
other things (pdf is not the only format they do) but the plenty
dependencies make that i am not too motivated to look into fixing the
pdf bits (basics are there)
The 2 editors have demo versions, I don’t know what you can do with
them. I’ve a license of PDF Studio Pro (since it’s the only tool besides
Acrobat Pro that can check & convert PDF/X).
i have no application so i rather spend my money on cd's, books and concerts
Apple’s Preview allows to include a manual signature. I would be
surprised if that counted as a valid digital signature.
Apparently Wondershare, PDFgear, and Sejda do the same.
with all these tech companies pleasing dictators soon there is little
untainted hard- and software for me to choose from ... so i can't check
apple
I found https://www.bytesigner.in that is apparently aimed at big
companies, they don’t even name a price.
that's the point: the tex/pdf world is basically not interesting and/or
considered as there is money to be made elsewhere (has always been the
case with pdf) which then involves marketing and who likes that
which is why in the end we need to keep tex a bit invisible .. away for
the competing markets .. not distraction .. so we just support/adapt-to
what is needed, e.g. wrt signing and move on
