Silverlight is a technology for creating Rich Internet Applications from Microsoft. The technology is almost similar to Adobe Flash but with some differences. With the Silverlight tool, you can create powerful web applications. However, for running such apps on macOS, Windows, or Linux, you need a suitable plugin for Silverlight.

In recent years, Silverlight has been losing its popularity. If you once installed Silverlight but do not use it now, we recommend that you uninstall it from your Mac.
