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.
