I'd like to watch Netflix on my 5,1 Mac Pro - but as you may or may not know, Netflix plug-in free with Safari is only for Sandy Bridge or newer Macs. I'd like to steer clear of anything having to do with Flash Player (Google Chrome) - but would Google Chrome be more secure - even with Flash - than Microsoft Silverlight? Are there any security issues with Silverlight? Is it something I'd need to disable when not on Netflix if I use it [Silverlight] with Safari? Thanks!
