What is Wireshark?
Wireshark is the world’s most popular network protocol analyzer. It is used for troubleshooting, analysis, development and education.
What’s New
We do not ship official 32-bit Windows packages for Wireshark 4.0 and later. If you need to use Wireshark on that platform, we recommend using the latest 3.6 release. Issue 17779
If you’re running Wireshark on macOS and upgraded to macOS 13 from an earlier version, you will likely have to open and run the “Uninstall ChmodBPF” package, then open and run “Install ChmodBPF” in order to reset the ChmodBPF Launch Daemon. Issue 18734.
