KidsServer shows promise of being more flexible than Kids GoGoGo (KGGG) with easier addition of allowed URLs and various filter subtypes. It also can filter all browsers unlike KGGG. Database is updated automatically several times a week. Biggest negative is that it uses a software proxy server which HAS to be set in the network system preferences. So anyone with administrator priviliges can bypass this in a second--including your kids or addicted adult!!! KidsServer needs to have an optional, password-protected, total blockage of all internet activity if the proxy server is turned off--even if by adminstrator or root user. The English is still very poor. Instruction is not clear on what to do with Kids GoGoGo if installing KidsServer. (Turing off KGGG does not work-- the "KidsSafe" process still shows up in Terminal under "top.") Installation is still in two steps which is confusing, and one is left unsure if all software installed. Finally, instructions on setting filter and URL preference are in poor English and leaves one in a state of befuddlement. Does one put in URLs with http:// preface, or just domain.com? and how does one separate URLs-- with commas, semi-colons, returns? I suggest Maki hire someone with good English to edit their entire website and software manuals. Unfortunately, there are no other competitors for this type of software in Os X. KidsServer requires an annual subscription of at least $40/yr. The efficacy, clarity, and ease-of-use must greatly increase to be worth that investment. Until the KidsServer proxy server cannot be bypassed, I suggest sticking with KGGG. Adults with internet addictions, may want to give spouse/friend password control over KGGG.
