Clean, elegant multi-use plugin. Microsoft got it right here. They're really no more the Evil Empire than any other scarcity-based, fear-mongering capitalist outfit, i.e., all U.S. businesses, including Apple. This is superior to Flash in every way

A lot of services require that you use this software to run things such as Netflix.

Any service that requires Silverlight at this time is:
A) Not paying attention to the fact that Microsoft themselves has declared Silverlight at EOL: End of Life.
B) Required to move to OTHER technology immediately.
C) Endangering their customers.

If you're stuck using a service using EOL Silverlight, TELL THEM IT IS *DEAD* and to stop using it NOW. Have them to go Microsoft's site NOW to verify that Silverlight must no longer be used anywhere for any reason as per Microsoft's dictum.

Microsoft themselves recommend that people NOT use Silverlight. They're going to discontinue it in time. Therefore, if you have it installed, ask yourself whether you actually need and want it. If not, then UNinstall it and save yourself from the potential security risks of having it installed.

Oh again. Installer ofvMicrosoft Silverlight downloaded from Macupdate contains malware that Virusbarrier block and alert. Why Macupdate decide to do all this inclusion of adware IR malware in the installer without notice to user?ni am a paid subscriber to Macupdate, and even I have set to block ad from Macupdate profile, the malware skill sneak in without notice I have to be very careful now with download from Macupdate. After all trust is hard to build but easybtondestroy. Think about this Macupdate!

Sadly, this is still needed here in the UK: Ordnance Survey, the national mapping agency, specifies it for their useful online application "get-a-map". There used to be a workaround, but that's now been blocked. Now why would they do that?

Version 5.1.40416.0, dated 12 May 2015 can't be opened under Yosemite without changing default security settings. Humm...Miscosoft fixes their security problems by delivering a non-conforming package? Is there a technical reason that justifies this? No README in disk image - just Silverlight.pkg. Will not be installing until clarified.

A closed source plugin for your browser. From Microsoft. Deprecated since 2011. Enough said. Sadly a few (usually very badly written) web pages and web apps still use it for some reason.

Unfortunately Amazon instant video (and Prime) has discontinued Flash support (which worked well on Mac) and now only allows Silverlight in both Firefox and Safari. Silverlight performance on my 2010 Mac Pro with GeForce 760 video card is very poor, it drops frames and stutters and the quality is low. And I was really looking forward to the new Amazon exclusive show starring the former Top Gear presenters coming in 2016. Now I may not be able to watch unless I choose to give up the great add-on ecosystem of Firefox in favor of Chrome.

If you need to support Microsoft's intranet solution "SharePoint", you still need SilverLight, too.

I have recently been getting some highly suspicious dialogs apparently relating to a Silverlight update appearing on my Mac without doing anything to trigger them (like checking for updates, for example). The title is "Microsoft Silverlight Update Available" and it carries on with some text encouraging me to install it. There is a very generic application icon within the dialog but nothing else, and certainly nothing that gives me any confidence that this is genuinely from Microsoft. Every sinew of my body is telling me this is bogus - surely Microsoft of all people would not issue an upgrade prompt that is one of the least believable I have ever seen? There are only two alternatives at the bottom of the dialog - "Remind Me Later" or "Update Now". What is the verdict of others?

Another angle on this is that if this dialog is a genuine upgrade prompt from Microsoft, it would be incredibly easy for someone else to fake it and this could represent a very credible way to socially engineer someone to install malware. On the back of this valid fear I have now uninstalled Silverlight entirely as I want to know for certain that any dialogs of this type can and should be ignored. You might want to consider doing the same!

Thank you for your comments! I've noticed this behavior (or at least something similar) myself over the past month or two. Something "off" about the message. Your thoughts coincide with some "interesting" app behaviors, such as PDFPenPro being a fanatical tracker.

Your comments inspired me to check "under the hood" for my Netflix and other video playing, and I'm pretty much migrated to using HTML5 with ClickToFlash extension, with the intention of getting away from Adobe Flash as much as I can - I notice it's working with Netflix, without any performance issues I can see, even with streaming set at the HD setting.

So maybe I can dispense with Silverlight as well?

Thanks,
