I’m trying to make a disk image, friendly both to dark and light system modes. I don’t see the way to do it in DropDMG, so I actually wonder if that’s currently possible. There are two obstacles:
1. The disk image should have a custom background in the window (icon view) when it mounts. So, I created an image with the transparent background, hoping that Finder’s icon view background would be visible underneath to automatically get light/dark mode. However, the window background underneath the image is always white. Even if I remove the background image completely, the background of the window stays white.
2. File names text are always black (and match always white window background from 1). I don’t see any option to make them match the system colour mode (that is, to let the Finder do the its things with text colour).
