 <p>The application identifier of an app "looks something like an Internet domain name in reverse, such as 'com.apple.textedit'."<a href="http://macscripter.net/viewtopic.php?pid=96491" rel="nofollow"> &rarr; reference</a></p> <p>If you used Xcode to create your Applescript application you can set the Application Bundle Identifier as part of the application setup wizard or in the Application Target properties. If you used the Applescript Editor to write your script and save it as an application your bundle won't have an identifier but you can add one.</p> <p>CTRL-Click on your application bundle and click Show Package Contents. Click on the Contents folder and then open the Info.plist file. This file specifies properties of your application in XML format. If you have Xcode installed it will open the file in the Plist editor making it a little more friendly to edit. What you want to do is add the CFBundleIdentifier key and your Application Identifier as the value. For example:</p> <pre><code>&lt;key&gt;CFBundleIdentifier&lt;/key&gt; &lt;string&gt;com.depot6.showworkingdrive&lt;/string&gt; </code></pre> <p>Add it near the CFBundleName key/value pair under the element. Saving the modified Info.plist will allow you to target that application in your Dashcode widget.</p>
