JBRANDX  Safe Eyes is hands down the worst software I have ever used on my mac. It is full of holes with constant problems. Always freezing up. I can only browze for about 20 Min before it starts blocking everything and I have to restart. There is a known problem with macs sleeping (I was told this by their tech support) and apparently no plans to fix it. In most cases after sleeping I have to restart in order for the program to work. It is constantly blocking sites that it shouldnt be blocking such as ebay or news sites (when I go to try and fix it the sites are catagorized correctly it is just blocking catagories that I havent told it to block). The tech support is always pleasent on the phone, and quick to respond by email. However, tech support has 2 major problems (their hours end at 5pm eastern time, I am in utah...) and the other problem is, that as nice as they are they still cant fix my problems- time after time. I would reccoment Content Protect for your mac. It is more expensive but well worth it.
