DropDMG 3.7.1
November 11th, 2025 (DropDMG)Version 3.7.1 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:
Fixed a bug where the Dock icon didn’t adapt to different themes on macOS Tahoe 26.- Fixed a regression where creating a disk image with a layout could affect the visibility of the path bar in subsequent non-DropDMG Finder windows.
- Improved the layout of the Software Update… sheet on macOS Tahoe 26.
- Worked around a Help Viewer bug on macOS 14.
Fixed the icon margins in the legacy ICNS file and documentation.- Added an Apple events usage description for the
dropdmgcommand-line tool. - Made various updates for Xcode 26.
DropDMG 3.7.1 works with macOS 10.13 through macOS Tahoe 26. Older DropDMG versions are available for older versions of macOS. In-depth information about DropDMG is available in the manual.
