Scripts to generate a DMG image disk for mac usually copy a .DS_Store file with folder customizations (icons sizes, positions, image background, etc.) You customize a read/write copy of the DMG, then copy the .DS_Store and use it to automate the DMG generation. It seems .DS_Store made in Leopard doesn't work in Snow Leopard and viceversa. A DMG created in Snow Leopard won't show the background image in Leopard. Is there a way to made a .DS_Store file that works in both OSX?
