Wireshark on Mac OS X (Snow Leopard)

Get binary: http://www.wireshark.org/download.html (I got 1.4.2)

• Install .DMG
• Copy the ‘Utilities’ folder from the DMG to /usr/local/bin
• Copy the entire ‘ChmodBPF’ folder to /Library/StartupItems/
• sudo xattr -r -d com.apple.quarantine /Library/StartupItems/ChmodBPF
• sudo chown -R root:wheel /Library/StartupItems/ChmodBPF
• Restart your machine, then it should work.
