ContentBarrier X 10.1
This is an Internet content filtering and parental control solution for your Mac.
Predefined categories let you choose what you don't want your children to see, and you can also create custom categories.
The content barrier blocks adult Web sites, sites with subjects not fit for children and chats in which predatory language is used. The program works for multiple users; if you have several children, you can set different criteria, corresponding to their ages and maturity levels.
You can choose whether they have access to newsgroups or download files. You can set the program to let them only use the Internet at certain times, on specific days.The program can even send you e-mail, automatically, when certain events occur.
ContentBarrier keeps a complete log of all Web sites visited, whether or not they are blocked.
