I had exactly the same problem. Seems as if the patch is missing the correct path. Could it be that your user name is not the same like the name of your user folder?! If you open the patch with 'Text Edit' you can manually adjust the name of the user folder. Save the corrected patch and run it again. You will see it will work! Good Luck! RS_PATH="/Users/Name of user folder/Library/Application Support/Steam/steamapps/common/Rocksmith2014/Rocksmith2014.app/Contents/MacOS"cd "`dirname "$0"`"cp ./libRSBypass.dylib "$RS_PATH/"./insert_dylib --inplace "$RS_PATH/libRSBypass.dylib" "$RS_PATH/Rocksmith2014"
