I'm brand new to OS X and Macs, so please forgive me if I'm missing something basic, but I'm pretty computer-literate and I'm stumped by something that seems like it should be pretty basic. When trying to view a movie trailer from the Apple site, nothing happens. The screen loads, and I get a backsplash from the movie, but no quicktime video can be seen anywhere. I can't see any links to click to get to the movie. The "how to" tutorial videos on apple.com work fine. I've tried Safari and Chrome, neither are working. What am I missing? I'm on a 27" i5 just purchased today. Thanks in advance!
