Sucks when a Silverlight update breaks Netflix. This should be all you need to re-install the previous version and keep you going until a fix is released.
-
Download the previous version from a trusted source. You can find the preivous version by visiting the Release History page and Googling for it. For example "Silverlight for Mac 5.1.20913.0" was available on the Techspot site.
-
Close all browsers, including this tab/window.
-
Delete each of the following files and folders. You can browse to each of the paths by pressing
SHIFT+CMD+Gand entering the path./var/db/receipts/com.microsoft.SilverlightInstaller.bom
/var/db/receipts/com.microsoft.SilverlightInstaller.plist/Library/Internet Plug-Ins/Silverlight.plugin~/Library/Application Support/Microsoft/Silverlight -
Now open up the file you downloaded in step 1 and run the Silverlight installer.
If all went well Netflix should now work just fine. If not, you'll need spend some time on Google.
