How to Use Wireshark on Mac Sierra

Wireshark is a powerful network protocol analyzer that allows users to capture and analyze network traffic. On your Mac Sierra, you can easily install and use Wireshark to troubleshoot network issues or monitor network activity. Here's how:

To start using Wireshark, first ensure that you have administrative privileges on your Mac. Next, download the latest version of Wireshark from its official website and follow the installation instructions.

Once installed, launch Wireshark by searching for it in Spotlight or navigating to Applications > Utilities > Wireshark. When you open Wireshark for the first time, you'll be prompted to enter your administrator name and password to confirm that you have permission to use the application.

Wireshark's main interface is divided into several sections. The top section displays the capture settings, including the interface you want to capture from, the capture filter, and the packet size limit. Below this section is a list of captured packets, which can be filtered by various criteria such as protocol, port, or byte pattern.

In the bottom section of the window, you'll find the packet details pane, which displays information about each selected packet, including its timestamp, source and destination IP addresses, protocol, and packet size. You can also use this section to apply filters to your captured data.

Logging continues even when you quit the app or restart your Mac, so remember to disable logging when you're done. The log file will be saved in the diagnostics report location on your Mac.

In addition to its capture capabilities, Wireshark includes several other features that can help you analyze network traffic. For example, the 'Info' menu provides detailed information about your current network connections, while the 'Wireless Diagnostics' menu allows you to perform additional analysis using tools like AirPort Utility and Network Utility.

To access these tools, open the Wireless Diagnostics window by pressing and holding the Option (Alt) key, then choosing Open Wireless Diagnostics from the Wi-Fi status menu. You can also find more information about your network connections by clicking on the 'Info' button in the top-right corner of the Wireshark window.

Overall, Wireshark is a powerful tool that provides valuable insights into network traffic and activity. By following these steps, you can easily install and use Wireshark on your Mac Sierra to troubleshoot network issues or monitor network activity.
