I am having trouble with my Mac and can't find the right fix anywhere. I can't make YouTube videos full screen or watch Netflix. I have uninstalled and reinstalled Silverlight multiple times. I have uninstalled and reinstalled flash. I have cleared my cache and reset Safari. I have tried downloading Chrome and Firefox and both did not work. I have a MacBook Pro 13 inch 10.6.8 2.4 GHz Intel Core 2 Duo and 4 GB 1067 MHz DDR3. I am also running Snow Leopard.
