Version 3.5.10 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 the chosen signing identity is no longer available, DropDMG will now show it in the Signing pop-up menu in red (instead of selecting Unsigned) so that you can see that creating the disk image with those settings will cause an error.
• Fixed a bug where the Finder window height was one point off on macOS 10.14 and later.
• Updated the Layouts section of the manual.
• Updated the Chinese localization.

DropDMG 3.5.10 works with macOS 10.7 through 10.15. Older versions are available for older versions of macOS. In-depth information about DropDMG is available in the manual.
