Access OS X's Packet Sniffer with the Wireless Diagnostics Tool

We've shown you how to tap your network and monitor everything that's happening before. However, blogger Jacob Salmela's shows off a trick that makes it even easier using OS X Yosemite's packet sniffer.

To access the packet sniffer, open up Wireless Diagnostics (hold down the Option key, click the Wi-Fi icon in your menubar and select "Open Wireless Diagnostics"), then click Window > Packet Sniffer.
