Hello fellow mac and tech lovers I've got a problem. As most of you guys here, I love gadgets and I love to know about apple. The thing is, I've got this thesis to write and I can't control myself to not watch engadget, macrumors... all the time while writhing my thesis on my computer. Is there a way to block certain websites with a timelock? For example: needing a password when visiting engadget.com between 4 a.m. and 8 p.m. Thanks!
