Setting Preferences:

Select the Preferences… menu item from the Apple Menu.
You’ll see two checkboxes.
Set the Automatically quit the Finder checkbox if you’d like the System 7 Pack! to automatically quit and open your Finder when the program opens.
Set the Automatically Save Changes checkbox if you’d like the System 7 Pack! to automatically save your changes. When unchecked, the System 7 Pack! will ask you if you want to save changes when you quit or close the Finder.

Press OK when you’re finished setting preferences.
