Quickly create disk image (dmg) archives.

Overview

DropDMG is the easiest way to create macOS disk images, which pack entire folders or disks into a single compressed file, either for transport across the Internet or simply for backup. They are Apple's preferred format for distributing Mac software. Disk images are also the only archive format whose contents you can directly access in the Finder. Just drag-and-drop a folder or file, and you're done. Or, you can drag an existing disk image or archive onto DropDMG to convert it to any of the other supported formats or to burn it to CD or DVD.

DropDMG supports advanced options such as signed, encrypted, and segmented disk images; WYSIWYG layout with background pictures and custom volume icons; and rich-text license agreements in multiple languages. There are many time-saving features, and it can also be automated via AppleScript, the command-line, and Automator.

What's new in DropDMG

Version 3.5.9:
  • Worked around a bug in macOS 10.15 that could prevent a custom volume icon from being saved.
  • Worked around a bug in macOS 10.15 that prevented the Set Passphrase… sheet from working from within the New Blank Disk Image… panel.
  • Worked around a bug in macOS 10.15 that prevented licenses from being removed when converting a disk image using license None.
  • Worked around a macOS bug that could prevent DropDMG from launching after you used AirPlay.
  • Worked around a macOS bug that could cause the Command-line tool to fail with error Killed: 9 after being updated to a new version until the Mac was restarted.
  • Fixed a bug where the passphrase sheet could be stretched vertically.
  • Modernized the localizations.

Switched from iDMG because DropDMG is still well maintained. Great application.

I don't know what's going on, but it's having trouble with 10.12.1 macOS Sierra. Took a very long time to create a blank, encrypted DMG (that wouldn't eject until I forced it in Terminal) while Apple Disk Utility did it in seconds without any trouble. Same thing with a different computer as well.

Please contact us at dropdmg@c-command.com with some more information so that I can look into this. I've not heard other reports of these problems, and I just tested this on my Mac with 10.12.1. The times were very close, and there was no problem ejecting the .dmg.

I think I might have accidentally used the new beta file system in Sierra for the DMG or had some other issues. It might just be all the junk I had running on the computers at the time along with some experimental tasks unrelated to DropDMG. I'll recheck it later and report to you if it's an actual issue with DropDMG and not just some esoteric issues on my end.

This seems to be mostly a GUI version of the hdiutil command, that is part of the OSX Unix command structure. Those who want to try their hand at it can create a Service using Automator and the "Run Shell Script" action item with the following command for a simple version of this (ignore brackets):
{hdiutil create -fs HFS+ -srcfolder "__OBJ_PATH__" -volname "__OBJ_NAME_NO_EXTENSION__" "__OBJ_PARENT_PATH__/__OBJ_NAME_NO_EXTENSION__"}

I used a free, old but reliable product called "On My Command" from Abracode to get this service. It is item 509 in the command listings. I have been using it for years. It makes it very handy and fast to have as a Service as opposed to an App.

Can also do Image compacting, although not so convenient to use but it does the job.

I think we can keep this one fairly short... The functionality is superb. It works and once its set up I can't imagine for a second it could be any easier to use. But by all the gods its a user experience train wreck. You will figure it out, you will absolutely feel that you have spent your money wisely... you will, at points, think the developers could think about the information architecture of the app. Buy it, there's nothing better.

Thanks for the review. It sounds like you were expecting a different sort of workflow. If you have a moment, we'd like to hear some more specific feedback at dropdmg@c-command.com.

I am upgrading my former comment of DropDMG. This software is not expansive at all. Just look at the help page: http://c-command.com/dropdmg/manual-ah/ You can try it one month, definitely not the MAS. The devoloper work on MAC since at least 12 years. If we want good product we have to pay for it. I don't work for free. The support seems very good to. I bought it.
