  • Fixed a bug where the command-line tool and Automator would time out during long disk imaging operations.
  • Fixed a bug where disk images with layouts sometimes ended up with too short a window.
  • Fixed a bug where creating a disk image with a layout would sometimes fail if DropDMG was running with root access.

  • Improved the error message when the chosen destination folder isn’t writable.
  • Improved the German localization.
