I'm having a a 2013 model 27" Mac, OSX 10.8.4, with Flash Player version 11.8.800.94. It won't let me record, and sometimes not play either, video and audio through an integrated Flash Player in a certain website. I've tried both Safari and Firefox, no joy. Safari version is 6.0.5. When I get to the page where the recorder is implemented, it is displayed as normal, but only says "loading". The Flash player plugin works perfectly in any other web page I have tried, including the test pages on Adobes pages. If I try the same webpage with the Windows laptop I've got (yuck...) it works without any issues.
Now, to make this even more complicated, the issue is valid only for two out of the five accounts we have. Both these accounts use the Parental Control feature in OSX, but I have made it as liberal as possible, and specifically allowed everything for the webpage in question. However, I have a third account with parental control where this is not an issue... I have also tried to remove the parental control with no luck. I have checked all the settings and Global Settings for Flash Player, and made sure everything is allowed.
I guess making a new account could maybe solve the problem, but there's got to be another way?
