(Note: this tip works in both Tiger and Leopard.)
If you’re like me, you’ve downloaded a bunch of widgets for your Mac’s Dashboard that you no longer use. Pink Floyd Reunion Tour Watch widget – never mind, they’re never reuniting. Expos baseball schedule – they’ve moved to Washington DC and changed their name. John Edwards for President Widget – no longer useful (Was it ever? Just kidding. I liked him.)
It’s easy to deactivate a widget, but the icon for the widget continues to show up in the Dashboard menu at the bottom of the screen. If you want to clean up your Dashboard menu, it’s possible to permanently delete widgets. Click on the Finder icon at the left end of your Dock (or the top of your Dock, if you keep your Dock arranged on the left or right of your screen.) Browse to your Home folder, then open your Library folder.
Inside the Library folder look for a folder named Widgets. All the widgets you’ve downloaded are stored here. You can delete these widgets by dragging them to your Mac’s Trash, or by clicking on them and pressing Command-Delete, which will send the widget to the Trash. Once you empty the Trash, the widget is gone forever! Or at least until you download it again from http://www.apple.com/downloads/dashboard/
