I work with Automator and DropDMG a lot. My only annoyance I have with DropDMG is the inability to change a configuration file’s settings and overwrite the existing one. Currently, I rename the existing configuration by adding a 1 to it’s name then save the new settings under the old name. This is a bit tedious. To add to the frustration, Automator will crash if you have a configuration file chosen in an action but delete/rename it. This is a weird bug as Automator will crash even if the workflow is not running.
Maybe I’m missing something obvious and you can point me in the right direction.
