Version 3.4 of DropDMG is now available. This is a free update for owners of DropDMG 3.0 that includes the following enhancements:

• Added support for creating disk images that are signed for Gatekeeper, as Apple now recommends that Mac applications be distributed on signed disk images (requires Mac OS X 10.11.5 or later). Unsigned disk images are subject to Gatekeeper Path Randomization. This is described in the Signing section of the manual.
• Added support for the .xip archive format, which lets you create secure archives that are signed for Gatekeeper (requires Mac OS X 10.8 or later).
• Added the Verify Signature… command for checking disk images and .xip archives to make sure they are correctly signed (requires Mac OS X 10.11.5 or later).
• The New Blank Disk Image… command now lets you choose the File System, which can be any variant of HFS+ as well as Apple File System (APFS), Apple’s experimental next-generation file system for 2017. This feature is particularly useful for developers who want to test that their apps work properly on each file system.
• On macOS 10.12, DropDMG no longer shows its Select Next Tab and Select Previous Tab menu items because they duplicate the new system ones.
• Made various code modernizations.
• If getting authorization fails, DropDMG now reports the command that it was attempting to execute.
• The distribution disk image is now signed.
• Updated the Sending in an Error Report section of the manual.
• Renamed “Mac OS X” to “macOS” throughout the app and documentation.
• Updated the Chinese, French, and Portuguese localizations.

DropDMG 3.4 works with Mac OS X 10.6.8 through macOS 10.12. Older versions are available for older operating systems.

For more information, please see the DropDMG Manual.

DropDMG 3.4 has not been submitted to the Mac App Store, due to the same code signing issue that affects DropDMG 3.3.
