The developers of Growl, a popular notification system for OS X that’s been around for years and it’s completely free to use, have announced that the plugin is going to become a Mac App Store application through a complete rewrite with OS X Lion in mind, dropping support for older frameworks and “hacks” like GrowlMail and GrowlSafari that wouldn’t probably make it past Apple’s approval. For those not familiar with Growl, the notification system became popular among Mac users because of its highly customizable nature that enabled almost anyone with basic coding and design knowledge to create “themes” for it that changed the appearance and animations of the notification tickets displayed on screen. Growl is supported by hundreds of different applications for the Mac, including big names like Twitter and Dropbox. We have covered a handful of beautiful themes for Growl in the past, and the success of this plugin also inspired several iOS developers to create mobile apps capable of plugging into the desktop system to fetch or send remote notifications. Growl is the undiscussed king of notifications for OS X apps.
Yet the developers are willing to change everything about Growl to get it ready for the Mac App Store and turn it into an app as requested by Apple to developers submitting software to iTunes. In a post on Growl’s official Google Group [via Steve Streza], developer Christopher Forsythe has announced that the upcoming 1.3 release will bring important changes such as the aforementioned Store availability, as well as full support for Lion and a new “app” form that has the obvious advantage of allowing users to easily upgrade to new versions by simply checking on their Mac App Store purchase page. One of the common complaints about Growl, in fact, is that the app often requires the user to download and perform an upgrade. As the existing version comes with a .DMG file that contains an installer for a System Preferences panel, the current Growl 1.2.2 forces users to manually upgrade every time a new version is out. With the Mac App Store and Growl becoming “an app”, the developers want to eliminate the convoluted process of opening and mounting a disk image file, running an installer, and manually upgrading from System Preferences.
