How do you clear the DNS Cache in OSX Mavericks?
A friend of mine was having some issues clearing the DNS Cache on his OSX 10.9 Mavericks machine - the well known way of doing it in terminal:
sudo dscacheutil -flushcache
...it doesn’t work though in Mavericks....and it doesn’t tell you either:
I could feel his pain...Anyway, the method of clearing the DNS Cache changed with 10.7 OSX Lion. To do it with Lion, Mountain Lion or Mavericks you need to use the following command:
sudo killall -HUP mDNSResponder
Cunning hey? Also, if you do the right thing and have your normal day to day account without Administrative rights, you may be interested in this article:

If you’re particularly lazy...there’s an app for this.
