Mac users should use their Firefox or Chrome browsers whenever possible. Firefox and Chrome works well with our flash player if they are up to date.
For Mac users on OS X 10.7 and 10.8 on Firefox: Firefox does not render any flash at all on our player, Adobe's or even YouTube's player. Using different versions of flash does not seem to make any difference. So upgrade your Mac OS!
Time outs on a Mac could be caused by your firewall software. For example, if you are running Little Snitch on a Mac, it is very easy to accidentally close the Little Snitch popup without clicking 'Accept' when our plugin loads. If you don't accept the popup and close it instead, you may not be able to watch DingIt broadcasts.
