One of the major new features of Mac OS X 10.4 (Tiger) is Automator. It is a tool that lets you build workflows from actions that may be provided by Apple (over 200 are part of the Automator installation), by software developers -- or by you, following the techniques described in the second part of this tutorial. You can use Automator to automate repetitive tasks or to manage complex and rarely-performed tasks. If you have Mac OS X 10.4 (Tiger) or later, you have Automator. Jesse Feiler guides you through using the software, taking advantage of the actions you already have, and show you how to build your own actions ranging from simple to complex using AppleScript and other technologies.
