MacOS - Rename Disk Image Within DMG?

Recommended Posts

Posted · Original PosterOP

As the title, and forgive my naivety, however is there a method / utility which can change the name of the drive within a dmg in macOS?

When the DMG is mounted, macOS disk utility looks as though you can re-name it but doesn't allow for it be applied.

A quick google reveals this is by design.

Surely there has to be an app which will allow the drive name to be changed and then the dmg re-packaged to reflect the name change?

Here's a way I just figured out now:

1- Mount the DMG

2- Right click the drive in DIsk Utility, select "Image from <NAME>"

3- Set format to "read/write" then save

4- Mount the new DMG

5- Rename it in Disk Utility, then unmount to save

6- If you want to keep it read only, repeat steps 1, 2 and 3 while keeping the format as "read only"
