dmgbuild - A command line tool to build
This document refers to version 1.6.0
What is this?
dmgbuild is a command line tool to create macOS disk images
.dmg files). While it is possible to create disk images
easily enough from the command line using the
hdiutil program that
ships with macOS, there is no easy way to configure the appearance
of the resulting disk image when the user opens it. Some people have
used AppleScript to automate Finder to adjust the appearance, but
since Finder saves its
.DS_Store files asynchronously, it is hard
to guarantee that the changes will actually be saved when you want
them to be. It also means that you need a GUI session, with Finder
running, in order to build your disk image.
dmgbuild does not rely on Finder; nor does it rely on deprecated
APIs (like the Alias Manager functions). Instead, it uses the
mac_alias Python modules, which know how to
construct the relevant data in Python code.
