DMG Architect... Easily add your own custom window backgrounds, files and icons. Total WYSIWYG control of everything including background image and window location. Use any image for your container icon, not just .ICNS files. Even change the icon of files already added to a project. No artwork? No problem. Choose a theme from our gallery of backdrops and icons.
Build: Revise your project as often as you need and at any stage. Add and update text without editing your background images. Typos are painless to fix. Accessing your Mac's powerful security features is easier than ever - add encryption for extra protection. Don't forget the End User License Agreement. Putting legal notices where they belong is simple.
Release: Burn your project directly to CD or DVD, no need for other apps. Release your project as a tamper-proof disk image.
Good application but is not 64bit, so no running in Catalina (10.15). The developer no longer references the application on their website. Further support is not likely.
In all seriousness... you get what you pay for. Buy Drop DMG. I was using this app for some time, but in the end it was too unreliable, too restrictive, and just a little too quirky.
Drop DMG.
Works fine:
but IMMO with Mountain Lion it needs an update: an option to sign DMG's with an Apple ID !
Writing readme files to explain how to disable GateKeeper isn't a good idea. Developer, me , seems to be a poor coder.
