Do I need to install the latest plug-in for Silverlight if I upgrade my Mac to El Capitan? Netflix keeps prompting me that I need the plug-in for Silverlight(and now won't even let me "skip for now"), but I read that if you use Yosemite you don't need Silverlight anymore. So since I was also prompted to upgrade to El Capitan, I would like to avoid having yet another plug-in from Silverlight taking up space on my computer, and if upgrading to El Capitan(or even to Yosemite, I am still using Mavericks right now) would be enough, I would like to do that. Then again, should I even upgrade to El Capitan, or Yosemite... I am pretty satisfied with Mavericks.
