At the risk of sounding like an idiot.... I too can no longer watch YouTube videos via Safari. Could someone please tell me exactly how one "toggles Safari to 32 bit"?!?!?! This is supposed to be the solution, but I don't know how to do this. Thank you so much for your help.
Also, how will this change affect anything else?
Nothing wrong here with HTML5 or Flash videos, try reinstalling your FLash player.
Also Apple does nothing to the Flash player, if the controls are broken in Flash it is ether Adobe or Youtube that have caused the problem.
The above didn't work for me.
I had to toggle Safari into 32-bit mode. YT works again.
I know this is most likely related to adobe but Apple's (Steve's) childish refusal to embrace flash is really starting to piss me off.
I wonder if this has been resolved yet or not.
It has not. I just found this thread via google. Switching Safari to 32bit mode does work.
