✦ Why It Matters
Start using AirTool 2 on your Mac today to simplify Wi-Fi traffic analysis.
Key Takeaways
- Use Terminal CLI or Wireless Diagnostics for PCAP capture.
- Consider AirTool 2 for an easier capturing experience.
- Ensure your Mac is M2-series or higher for best results.
- Capture Wi-Fi traffic efficiently without external adapters.
Full Summary
macOS provides robust tools for network engineers, particularly for capturing Wi-Fi traffic in PCAP (Packet Capture) format. Users can utilize the Terminal CLI or the 'Open Wireless Diagnostics' feature by holding the Option key while clicking the Wi-Fi icon.
This opens a sniffer that automatically selects the current Wi-Fi channel and width. Alternatively, AirTool 2 simplifies this process with a user-friendly interface, allowing for easy selection of channel settings.
The application leverages the Mac's built-in Wi-Fi adapter, which means external USB adapters are not supported. For optimal performance, using an M2-series Mac is recommended, as it supports the latest Wi-Fi standards.
As of late 2025, no Macs support Wi-Fi 7, but the existing capabilities are still powerful for network analysis.
