DropDMG is the easiest way to create OS X 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 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.
- Added support for creating disk images that are signed for Gatekeeper, as Apple now recommends that Mac applications be distributed on signed disk images (requires Mac OS X 10.11.5 or later). Unsigned disk images are subject to Gatekeeper Path Randomization.
- Added support for the .xip archive format, which lets you create secure archives that are signed for Gatekeeper (requires Mac OS X 10.8 or later).
- Added the Verify Signature… command for checking disk images and .xip archives to make sure they are correctly signed (requires Mac OS X 10.11.5 or later).
- The New Blank Disk Image… command now lets you choose theFile System, which can be any variant of HFS+ as well as Apple File System (APFS), Apple’s experimental next-generation file system for 2017. This feature is particularly useful for developers who want to test that their apps work properly on each file system.
- On macOS 10.12, DropDMG no longer shows its Select Next Taband Select Previous Tab menu items because they duplicate the new system ones.
- Made various code modernizations.
- If getting authorization fails, DropDMG now reports the command that it was attempting to execute.
- The distribution disk image is now signed.
- Renamed "Mac OS X" to "macOS" throughout the app and documentation.
- Updated the Chinese, French, and Portuguese localizations.
OS X 10.6.8 or later
