Cut Down on Internet Distractions with “Freedom”

Freedom is a Mac OS X app that temporarily cuts off your network access so you can get work done. It disables wireless and ethernet networking on an Apple computer for up to three hours at a time, after which it re-enables your network, restoring everything as normal. The only way to circumvent Freedom during its imposed blackout is to reboot the machine; it’s believed that the hassle of rebooting will be enough to keep you doing it. Freedom is free as in beer, but if you find it useful, its makers encourage you to send a donation.
