I’ve always appreciated the effort and creativity developers put into making this a good experience, and a learning experience for new users. After all, you never know which app will be someone’s first install. A well made dmg was how I learned to install apps on OS X when I first moved to it 23 years ago.

Some developers have gotten lazy with this and expect users to just know. As a result I’ve seen many people running an app out of the dmg file itself for a long time, then they wonder why they have a bunch of stuff mounted.

Is the quote in the title a reference to something?
