I'm in the process of picking out a new imac for myself and will pass on my old one to my six year old daughter as soon as I upgrade the ram and install snow leopard. Now that she can read and get on the computer on her own, can someone give me a few quick pointers on making my computer a little more safe for her. Meaning: are there parental controls in snow leopard or safari that would block adult websites. I don't even know if they rate sites like tv shows and if its even possible to block any part of the internet. Any advice a parent who has done anything like this can offer would be very greatly appreciated.
