Applications on macOS are generally distributed inside a compressed disk image (.dmg) file. cx_Freeze allows you to go one step further and bundle your package into a DMG file directly.
This is done using bdist_dmg by executing the following command line:
python3 cxsetup.py bdist_dmg
This command runs bdist_mac and then packages the resulting bundle into a DMG file. The configuration options for bdist_dmg allow you to override the filename and include a shortcut to the /Applications directory for easy installation. The built file will appear in the build directory, and you can copy it from there to another Macintosh to be mounted and used.
