What is Wireshark?
Wireshark is the world’s most popular network protocol analyzer. It is used for troubleshooting, analysis, development and education.
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.

Wireshark source code and installation packages are available from https://www.wireshark.org/download.html.
Most Linux and Unix vendors supply their own Wireshark packages. You can usually install or upgrade Wireshark using the package management system specific to that platform. A list of third-party packages can be found on the download page on the Wireshark web site.
Wireshark and TShark look in several different locations for preference files, plugins, SNMP MIBS, and RADIUS dictionaries.
These locations vary from platform to platform.
You can use
tshark -G folders to find the default locations on your system.
The User’s Guide, manual pages and various other documentation can be found at https://www.wireshark.org/docs/
