How To Uninstall Silverlight in Mac OS X El Capitan, Yosemite, Mavericks. Silverlight was Microsoft’s alternative to Flash and Microsoft announced that they were to discontinue and stop active development on Silverlight. Of course IE 11 and Edge are Windows browsers only. I cannot tell you why Safari supports HTML5 on Netflix as of Safari in Yosemite or higher. But I can tell you that in El Capitan Silverlight has some real issues in full screen mode with Safari. Chrome has dropped supporting Silverlight and uses only HTML5 streaming for Amazon and Netflix.
I'm trying to get Silverlight to work on Mac OS X, any browser would do. I'm not getting much success at all so far, nor help from the Web. 1) Silverlight + Mac OS X Yosemite To start with, can anyone tell me if this Silverlight test works for them on Mac OS X Yosemite (10.10.1)? This should offer a menu and various content, mostly pictures. (As opposed to a big black square of nothing.) 2) Troubleshooting I'm using a MacBook Pro from Mid-2014.
I had Silverlight version 4 installed before but never got it to work (I don't know if this was before or after my Yosemite update.) I've tried uninstalling and re-installing Silverlight but without success. To install, I'm merely using the Silverlight.dmg file and its installer to install. Here is what I'm getting so far:.
In Firefox: the official 'Get Silverlight' page tells me the plugin is installed ('Silverlight 5 (5.1.30514.0)'), however the test page linked above renders black. FYI, the plugin is set on 'Always activate' in about:addons and disabling AdBlock did not help.
In Chrome: I had to use the 'Get more extensions' option inside of Chrome to install. However, the test linked above merely offers an 'Install Microsoft Silverlight' icon. In Safari, the test seems to render okay but then I get an error from Safari itself: 'A problem occured with this webpage so it was reloaded', leading to the page being reloaded automatically until Safari gives up and tells me that an error repeatedly occured with the page. Any pointer welcome.
I decided to look into uninstalling Silverlight which led me to your comment. In my efforts I decided to reinstall and try uninstalling again.
Since I just reinstalled I decided to try your link. I got the black box like you did with a little imposed box in the top left corner with silverlight printed in it. I clicked the little box and the big black box a couple of times, since I use click to plugin extension, and it loaded fine. Good Luck to you P.S. I am using a mid-2011 MacBook Air running Yosemite 10.10.2. I have been having the exact same issue on my Mid-2014 MB Pro. I am almost positive the problem does not lie in Yosemite itself but rather in the new machines.
Apparently new machines were formatted differently or something of the sort and no longer support Silverlight whereas older machines that simply upgraded to Yosemite from something even as recent as Mavericks do not have this issue. I work at an Apple Premium Service Provider and have spoken at length with Apple certified technicians on this topic and that's our conclusion. It sucks, really.
I'm running OS X version 10.10.5 (Yosemite) on my Intel based Macbook Pro. I've been using Firefox as a browser because I need to run Silverlight to access my gradebook on PlusPortals.com. Initially, there was no problem. However, I began to get spam tabs opening up that I wasn't able to close which had never before happened while I was running my Mac partition (I also run a Windows partition) and it freaked me out, so I uninstalled (or thought I did) Firefox after force quitting it. When I reinstalled the latest version of Firefox, Silverlight didn't show up on the list of plugins and I could no longer access my gradebook page using Silverlight.
No error messages, just a blank page. I managed to find Silverlight and it was set to always activate. I'm not sure how to fix it other than to completely wipe both Firefox and Silverlight from the hard-drive, but I'm unsure how to do that fully. I've dragged both to the trash, found the appropriate files in the Mac Library and dragged them to the trash and then emptied the trash securely. Still, when I reinstall, no dice and nothing seems to have changed.

Plus, when I look into the Silverlight plugin info, two identical files are listed making me think that there are two installations running at the same time and possibly causing the trouble. Any help would be great. The Category topics I had to choose from were stupidly unhelpful and so was the fact that I wasn't able to submit this question without choosing one.
