I have a white early 2008 macbook running Lion 10.7.5 (11G63). Whats the best way to mirror my laptop or stream from vlc to my vizio tv? I tried via hdmi with a mini convertor cable but it doesn't carry sound. For apple tv i saw that you have to have a macbook that is 2011 or later. Videocast won't open because my macbook is older. Thanks !
