Asked by Old McStopher
I know this may stem from a fundamental misunderstanding of the way disk images are intended to work, but even when full permissions are granted on a .dmg file, I am unable to add or remove files on the mounted disk image. Is there any way (natively or via a 3rd-party tool) to do this?
I know that when a disk image is mounted, a checksum verification is done, so I'm guessing that because modifying the image at all would destroy the checksum, this is inherently not allowed, but I'm wondering if there's a utility that could re-image the disk with a subset of its contents, perhaps recalculating the checksum in the process.
NOTE:Copying all the contents over, deleting, and then re-imaging is not a plausible option, due to the size of the image and the fact that it already fills most of the available space of the external drive on which it resides.

You can edit, add, and remove files on a Disk Image if it is formatted to be readable and writable, which is set at the creation of the Disk Image.
This is a different concept than file permissions: File permissions allow you to read, i.e. mount, an entire Disk Image, or delete it in entirety (as a Disk Image itself is a single large file). How the Disk Image was formatted sets the rules for if you can only read (or both read and write) files within the Disk Image.
To natively create a readable and writable copy of a Disk Image, you can use the hdiutil of macOS via Terminal.app like this:
hdiutil convert -format UDRW -o ReadableAndWritableCopy.dmg ReadOnlyOriginal.dmg
You can then edit what is in the ReadableAndWriteableCopy.dmg Disk Image and create another copy with your edits that is read-only (like the original was) like this:
hdiutil convert -format UDRO -o ReadOnlyCopy.dmg ReadableAndWriteableCopy.dmg

A disk image is designated as read-only or read-write when it is created. Simply changing the permissions on the DMG file will have no effect.
