Growl is a deprecated global notification system and pop-up notification implementation for the Mac OS X and Windows operating systems. Applications can use Growl to display small notifications about events which may be important to the user. This software allows users to fully control their notifications, while allowing application developers to spend less time creating notifications and Growl developers to concentrate on the usability of notifications. Growl can be used in conjunction with Apple's Notification Center that is included in Mac OS X 10.8 (Mountain Lion) and higher.
