That's one reason to put it under your home (personal, user)
directory. Normally, your TeX distribution will define a "user"
directory, where you can put stuff that is "just yours". In your
case, it's like to be something like /Users/stefan/texmf/, but I
don't know for sure, as I too am not on Mac. But if that were right,
then you could put your bib files in /Users/stefan/texmf/bibtex/
bib/, and they'd no more be lost on update than any of your other
"personal" files.
I think on the Mac, it's <user>/Library/texmf/bibtex/bib
(if the bibtex or bib folder does not ecist, just create it)
Would I have to add the path in the preamble then?
No.
Thanks again. I will save my files there from now on.
Best*
