On macOS 10.14 and later, you need to tell the system if you want applications
to be able to control other applications or access their data. For example:
- In order to create a disk image layout, DropDMG needs to be able to
control the Finder to set up the disk image’s view options.
- In order to create a disk image containing certain files in your
Library folder, you need to give DropDMG Full Disk Access.
- In order to create a disk image containing files certain folders (like
Desktop, Documents, and Downloads you’ll need to grant
DropDMG Full Disk Access or Files and Folders access to those
folders.
- In order to use the dropdmg command-line tool from Terminal, Terminal
needs access to control DropDMG.
