Version 3.6.3 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:

• Updated the Create macOS Install Disk prompt and documentation for macOS 12 Monterey.
• Updated the Format and Segments sections of the manual for macOS 12 Monterey.
• Updated the crash reporter for macOS 12 Monterey.
• The command-line tool no longer times out for very long operations.
• Improved DropDMG’s error handling when setting a custom volume icon and making the mounted disk image auto-open.
• Improved DropDMG’s error handling when reading license agreement information from a disk image.
• Fixed a bug that could cause a crash when updating the Activity Window when multiple operations were in progress at the same time.
• DropDMG now declares notch compatibility for the new MacBook Pros.

DropDMG 3.6.3 works with macOS 10.9 through 12.0.1. Older DropDMG versions are available for older versions of macOS. In-depth information about DropDMG is available in the manual.
