v2.0.2, for Mac OS X 10.7+

Users of older OS versions can download SelfControl 1.5.1 for Mac OS X 10.5+.


SelfControl is a free and open-source application for Mac OS X that lets you block your own access to distracting websites, your mail servers, or anything else on the Internet. Just set a period of time to block for, add sites to your blacklist, and click "Start." Until that timer expires, you will be unable to access those sites--even if you restart your computer or delete the application.
