Hey guys. My mom's in the market for a computer that my sister can use while I'm gone. I'm leaving for college this fall, and won't be able to help them with virus removal, and typical Windows maintenence. She agrees that a Mac would be a good solution. She's looking at a refurbished low-end iMac ($799) for just web browsing, email, Word, and pictures. However, since it's mainly for my younger sister, she requires that an internet filter be put on it, to block porn and racy chatrooms, as well as other questionable content. On her old PC, she uses American Familty Filter. Is there anything similar to that for Mac. Because I can't seem to find anything that's Mac compatible. Thanks.
