Version 3.5.7 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:

  • If setting a disk image’s layout fails, DropDMG will now report a better error message that explains how to enable Automation access in System Preferences, rather than just mentioning error code -1743.
  • Worked around a Mac App Store bug that prevented setting disk image layouts when using macOS 10.14 or later.
  • Expanded the Signing section of the manual with more information about the different kinds of signing, as well as notarization.
  • Worked around a bug in macOS 10.13 and later that can corrupt a custom volume icon.
  • Worked around permissions error that could occur when converting a disk image to an archive on newer versions of macOS.

DropDMG 3.5.7 works with macOS 10.7 through 10.15. Older versions are available for older operating systems. For information about previous releases of DropDMG, please see the version history.
