DropDMG
3.5.8Quickly 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
- The Create macOS Install Disk command works around some issues with the macOS 10.15 Catalina installer that could cause errors or the creation of incomplete installation disks.
- Create macOS Install Disk automatically shows you the volumes list when it’s time to select the destination volume, saving you a step.
- Updated the Create macOS Install Disk and Signing sections of the manual.
- When calculating the size of the source folder or app, DropDMG now counts the sizes of any extended attributes. This fixes a problem where some apps (e.g. those made using the Qt framework) that include large numbers of small code-signed files wouldn’t fit on the disk image.
- Work around a series of bugs in macOS 10.15 that sometimes caused a "Resource temporarily unavailable (-54)" error when creating a disk image with a license agreement.
- Worked around an issue with macOS 10.14 where the log detail drawer might be slightly too short to fit all of its contents without scrolling.
- If you have a disk image with a pre-existing license agreement and convert it with None as selected license, on macOS 10.15 the license is kept rather than deleted. This is due to a pair of bugs in Catalina (FB7362946, FB7362950).
- Fixed a crash that could occur if there was an error creating a macOS install disk.
- Fixed a bug that could cause a crash when a Software Update error occurred.
- Fixed a bug with the crash reporter window and Dark Mode.

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.
