How to make a .dmg file? I know how to make a .dmg file but I do not know how developers (Mostly games) create a window where there is the software file and sometimes theres a readme file. When I create, It shows just a normal finder window not like with custom background or where you can drag the folder anywhere on the finder window. How am I suppose to make that? I making a game and I really want to make it.
DropDMG

I use and recommend DropDMG since it has many features that make it useful for sharing software such as scripting the building of a DMG file directly from my CI server when I promote a build using the included CLI tool dropdmg.



Above: Many options for configuring a DMG file, including layouts and showing a license when opening the DMG.
