Hi Guys, It's been 3 days since I got my first mac ever. I find it strange, that I can watch only some youtube videos on my brand new haswell 15'' macbook pro... some of the videos work perfectly but others, safari keeps telling me that I need to install flash !!! An example of this, is the following youtube video: http://www.youtube.com/watch?v=oYOKp9j-_yY I can watch it on my iPhone 4s via Safari (iOS doesn't come with flash installed, right ?) I cannot watch this same video via Safari on my brand new haswell 15'' macbook pro (OSX Mavericks) Some thoughts most appreciated. Thanks.
