Apple currently recommends that ALL applications be delivered in the form of
an installer. See the "PackageMaker User Guide," last revised in July 2007:
"The installation packagebased mechanism is the preferred method for
delivering products in Mac OS X. This model is a change for experienced Mac
OS X developers and packagers. Before Mac OS X v10.5 (Leopard), the
preferred software delivery mechanism was the manual install, where users
drag the product from its container, a disk image, onto their file system.
However, managed installs (which are steered by the Installer application
after the user opens an installation package) on Leopard clients make
possible advanced installation-management features, such as better package
management through the Installer package database, downloadable packages,
and certificate-based signing. Leopard leverages these features to provide
users an improved install experience."
I don't have any inside information, but I assume this change is because so
many switchers from that other platform have difficulty with the concept of
drag-installing an application package.
This doesn't answer your question about DMGs, however. You can deliver an
installer in a DMG, as I do these days, or in a zip file, or whatever.
