The Growl Project has released Growl 2.1, adding the capability to run scripts as actions as well as control notifications via rules using AppleScript. (For more information on writing AppleScript for notifications, see this documentation page.) The system-wide notification utility also addresses a problem with hanging when receiving more than 100 notes at a time, enables use of styled close buttons on WebKit displays, localizes Automator actions, and displays notes on both computers when using forwarding with Notification Center forwarding. ($3.99 new from the Mac App Store, 6.8 MB)
Thoughtful, detailed coverage of the Mac, iPhone, and iPad, plus the best-selling Take Control ebooks.
