Silverlight 5.1.41212.0

Silverlight 是由 Microsoft Corporation 開發的 macOS 瀏覽器外掛，旨在提供跨平台與跨瀏覽器的互動式應用程式及多媒體體驗。它最顯著的特色在於能支援 AJAX、VB、C#、Python 及 Ruby 等多種程式語言，並透過強大的插件集與現有網頁應用整合。雖然目前已屬於停止更新的產品，但在同類工具中仍是相當熱門的選擇，且使用者評價普遍不錯。

這款免費軟體適合需要執行特定互動內容或開發舊版網頁應用的使用者。在瀏覽網頁時，若遇到必須依賴此外掛才能運行的媒體體驗，才會用到 Silverlight，而平時則可選擇 Google Chrome 或 Firefox 等主流瀏覽器替代。下載前請留意，此 macOS 版本僅提供英文介面，且在功能取捨上需視您所造訪的網站需求而定。

What`s New

• End of support: Microsoft ended Silverlight support on October 12, 2021, so there are no new updates, fixes, or security patches.
• Mac browsers no longer supported: Microsoft states there is no longer support for any browser on macOS (Silverlight ended up effectively being IE-only near the end).
• Safari 12+ broke Silverlight: Safari removed NPAPI plugin support, so Silverlight won’t run in modern Safari versions.
• Last widely referenced version: Silverlight’s final line is commonly listed as 5.1.50918.0 (legacy downloads only; not actively maintained).
• Practical “what’s new” today: it’s essentially legacy/obsolete on Mac—any “new” items are just third-party repackaging/hosting, not official improvements.

It had support for interactive elements, high-quality video streaming, and support for custom add-ons. Some of its biggest adopters were popular video streaming services such as Netflix and Amazon Video, who distributed their popular content to their end users via the Silverligfht-powered platform.

However, after only several years on the market, active development on this application framework stopped in 2012 with the last compatible browser for it being Internet Explorer 11 from 2013. Microsoft officially terminated support for Silverlight in late 2021.

Today, the Silverlight platform serves as a basis of experimentation by home enthusiasts and students, with very little of its content surviving on the modern internet.
