Awesome find! Half my reason for needing Windows is to convert PC CDLC to Mac. Now if it could add DD, I could ditch Windows altogether! I like all mine to have DD, so here's some more script-fu: Convert all DD-enabled PC CDLC to Mac and move to the proper dlc folder (my CDLC's tend to collect in ~/Downloads until they are ready): $ cd ~/Downloads # or wherever you have your PC CDLC $ find . -name \*_DD_p* | xargs -n 1 pyrocksmith --convert # convert all to Mac $ mv *_DD_m* ~/Library/Application\ Support/Steam/steamapps/common/Rocksmith2014/dlc Strip out the extra characters that confuse RS2014: $ cd ~/Library/Application\ Support/Steam/steamapps/common/Rocksmith2014/dlc $ for a in *[A-Z-]*; do b=$(echo $a | sed -e 's,-,_,g' -e 's,_v[0-9_]*\(_DD\)*_m,_m,g' | tr -cs "[:alnum:]" _ | tr "[:upper:]" "[:lower:]" | sed -e 's,_psarc_$,.psarc,g'); mv -v "$a" "$b"; done
