I have a PowerPC G5 with OS 10.5.8. I'd like to be able to automatically disable my internet connection after a set amount of time of usage (1.5 hours, 2 hours, whatever), but keep all programs usable, so the parental controls that limit computer usage are no good. I downloaded Freedom, but since it requires me to manually tell it when to disable the internet and for how long, it doesn't really work for my purposes. However, if I could have it automatically run 1-2 hours after opening Safari/Firefox, that would work too.
Alternatively, is there any other software out there that could do this kind of thing? I am looking into Intego ContentBarrier and Time Sheriff. Has anyone used these?
