DropDMG is the easiest way to create macOS disk images, which pack entire folders or disks into a single compressed file, either for transport across the Internet or simply for backup. They are Apple’s preferred format for distributing Mac software. Disk images are also the only archive format whose contents you can directly access in the Finder. Just drag-and-drop a folder or file, and you’re done. Or, you can drag an existing disk image or archive onto DropDMG to convert it to any of the other supported formats or to burn it to CD or DVD.
DropDMG supports advanced options such as signed, encrypted, and segmented disk images; WYSIWYG layout with background pictures and custom volume icons; and rich-text license agreements in multiple languages. There are many time-saving features, and it can also be automated via AppleScript, the command-line, and Automator.
- macOS 10.14 has new data protection features that require the user to specifically grant applications such as DropDMG access to do certain things. In general, you will want to grant DropDMG Automation access for Finder and possibly Full Disk Access as well. This is further explained in the Security & Privacy Access section of the manual.
