Version 3.6.6 of DropDMG is now available.

DropDMG makes it easy to create a professional disk image for your app. Disk images pack entire folders or disks into a single compressed file, either for transport across the Internet or simply for backup or archival. They are Apple’s preferred format for distributing Mac software and the only archive format whose contents you can directly access in the Mac Finder—no extraction or third-party software required.

Deliver your Mac app on a .dmg file with a software license agreement, a custom volume icon, and a precise icon layout atop a Retina-optimized background picture. Customers can install simply by dragging and dropping the app onto the convenient Applications folder link. Code-sign your .dmg so that macOS knows it can be trusted after download.

This is a free update for owners of DropDMG 3.0 that includes the following enhancements:

  • Settings: ConfigurationsWhen creating a New Blank Disk Image…, there is now a preset size for macOS Install Disk.
  • Worked around a macOS change that could cause the filename column of the log to be truncated.
  • Improved the Format section of the manual.
  • Settings: ConfigurationsAdded HdiutilFilesystem to the esoteric preferences. This makes it possible to use APFS when creating a disk image from a folder, which can make it faster for the end user to copy files from the mounted disk image.
  • Tried to work around a change in macOS 13 that could cause DropDMG to crash at quit if you had used the font panel.
  • Settings: LicensesFixed bug where setting a disk image to auto-open would sometimes fail when running on an Apple Silicon Mac.

DropDMG 3.6.6 works with macOS 10.13 through macOS 13. Older DropDMG versions are available for older versions of macOS. In-depth information about DropDMG is available in the manual.
