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?

You can block sites within fixed time periods (e.g., between 9am and 5pm), after a time limit (e.g., 10 minutes in every hour), or with a combination of time periods and time limit (e.g., 10 minutes in every hour between 9am and 5pm). You can also set a password for access to the extension options, just to slow you down in moments of weakness!

The sites to block can be specified using wildcards (e.g., * and exceptions (e.g.,

Meetimer might fit your needs. Lifehacker suggested it a few years ago.

That's a neat application, but it only tells you how much time you've spent procrastinating... it doesn't actually disconnect you or put a hard limit on your online time. Thank you, though! – LRZ Jun 25 '10 at 20:48

Switch of your modem, and turn it back on when you have fully completed all your work. ;)

The whole point here is to have an automatic solution. – Gnoupi Jun 30 '10 at 7:29
