Much of the time, it's just: 1 - Click a download link 2 - Do other things until the DMG opens automatically 3 - Click and drag the application into the link to /Applications right next to it 4 - Yes, I want to run this downloaded application, the first time you run it. Deleting the .dmg is something that I don't do as part of this process, but as part of a separate garbage collection process every few weeks.
