Mac, Minecraft and Parental Controls?

My pre-teen daughter loves to play Minecraft and so we gave her our approximately 5 year old MacBook to play it on. We got Minecraft working on it just fine. But then I turned on Parental Controls so that she couldn't use the laptop to see things she shouldn't and it stopped working. Whenever i turn Parental Controls off Minecraft works and whenever I turn them on it stops working. I tried adding "minecraft.net" to the safe website list but that didn't help. Does anyone have any ideas?

Get a monitoring tool for the Mac to see where incoming network traffic comes from. Make sure only minecraft is running while doing this check and see which sites it access. Also, if your daughter plays online, on servers, I'd recommend you to download a third party parental tool that can allow certain programs to have full network access (and disable Apple's own).
