Silverlight is a Microsoft browser developed for Internet plug-ins and other online applications, such as Netflix's streaming video player. Formerly a strictly mail-order DVD rental service, Netflix also offers streaming video of thousands of titles available to watch in any popular Internet browser. If your browser or operating system is incompatible with the Silverlight platform, however, Netflix offers streaming video on a long list of Netflix-ready devices, including video game consoles and mobile phones. Browse the list of Netflix-ready devices.
When you locate your device, click the corresponding 'Learn More' link to view a list of basic information and instructions to connect your device with Netflix. Each set of instructions is unique to each device; however, a common step shared by all of the Netflix-ready devices is that you will need to verify your account information. Certain consoles and systems additionally require you to connect your account with a device activation code, available once you begin the installation process for the device.
Silverlight not working I've read through the posts here & can't find the answer. I install Silverlight, shows as added program then go back to Netflix to view movie & get the same message to download Silverlight. The current version of Google Chrome is running Netflix just fine on my mac. (mid 2010 mini, 10.13.6 High Sierra) That's the only work around I know for older macs, according to Netflix newer macs will show video in html5.
