text: how do i block a website on a macintosh computer? i need to block access to a specific website on a macintosh computer. i have blocked the website from all of our pc's in the office by editing the "hosts" file, which worked great. however, i cannot figure out how to do it on a macintosh. any suggestions? some will probably suggest "internet tools" and then "security" and add the website to the restricted list, but that doesn't block it... i need a way to completely block it. thanks! a number of third party macintosh utilities can do this.  one popular program with good user reviews is intego's contentbarrier x.  http://www.intego.com/contentbarrier/
