Mac’s own firewall does not block outgoing connections of any application. It can only block incoming connections. But sometimes we need to block outgoing connections as well for total control. There are few paid applications like Little Snitch or Hands off! which are doing really good job. But who needs paid applications when we have free application for this purpose.
TCPBlock is totally free and it can block outgoing connections as well as incoming connections of any Mac application. TCPBlock for Mac requires OSX 10.6 or later.
