Do exactly like for the package etoolbox, i.e. create adirectory 'biblatex-dw' in ~/Library/texmf/latex/
It still doesn´t work. Could it be, that I have to enter the content of the folders of biblatex-dw into the corresponding ones of etx-> latex->biblatex, like the content from "bbx" in biblatex-dw into "bbx" of biblatex?
I add an image to illustrate what I mean:
<<inline: Folders.png>>
I mean to put the coontent of the green folder directly into the yellow one.
