How to Uninstall Silverlight on My Macby Jason Taetsch
The Silverlight programming language is used by developers to create interactive menus and features for applications and websites. Unlike other programming methods, Silverlight requires an application to display the features. Remove the Silverlight program on your Mac if you are upgrading to a new version of the software or if it is causing errors on your computer. Mac OS X stores application files in a single location so you can quickly uninstall a program in just a few clicks of the mouse.
Click the "Finder" icon on the dock.
Double-click the "Applications" folder.
Scroll to the "Microsoft Silverlight" entry. Click the entry and drag it onto the "Trash" icon.
Click the "Finder" icon and click "Empty Trash" to uninstall the Silverlight application from your Mac.
