Safari complaining when trying to view WWDC videos
Despite running Mac OS X Mountain Lion and Safari 6.0.5, whenever I attempt to play a video from Apple's Developer WWDC site, I receive the following error:
System Requirements
To watch the streaming version of this video, use the latest version of Safari on a Mac running OS X Lion or later. Alternatively, you can watch this video in the WWDC app or download the video when available.
I instead force to download the video.
Any suggestions?
iMac, OS X Mountain Lion (10.8.5), 27" Intel Core I5 - 4GB ram
