title: How do I package a Mac OS application for install?
body: <p>I know on windows there are a bunch of installer tools you can use to create an installer, but on Mac OS I've seen two ways to install apps:</p>
  
  <ol>
  <li><p>A DMG file which you download, double-click, then run an application inside - the application typically has you drag an icon to another icon (representing the Applications folder) to install the app</p></li>
  <li><p>Another type of file which launches an apparently standard installer, which sometimes brings up a warning like "This installer may run a program to determine if you can go ahead with the install"</p></li>
  </ol>
  
  <p>What's the "standard" way of packaging an app for install on Mac OS? Is one of the above the Apple-recommended way?</p>
  
  <p>Thanks.</p>
