I tried this
\graphicspath{{/Volumes/MacHD2/'Messprojekte HD2'/Ensmad/Bericht/Bilder/}}
but it doesn't work. Okay, I could rename that directory, but would prefer not to do this.
I need a 'global' solution, I don't want to edit each of the 65 lines with \inclegraphics as you can see in the possible duplicate.
\usepackage{grffile}works at least on windows in a current miktex/texlive, I tested it with\graphicspath{{test with space/}}(but the fact that I had to test shows you that I normally avoid spaces like the pest). – Ulrike Fischer Nov 17 '16 at 08:24
