This video will show you how to run a packet capture using Wireshark on OS X. There's a separate video guide for Windows users. If you'd like to find out more, see our Wireshark Guide.
As of early March 2010 Wireshark version 1.2.6 runs under Snow Leopard but will not open a capture. There are workarounds detailed on the web but these involve what I think are expert level changes to Unix system files and I chickened out! Hopefully by the time you read this all will be well.
