The Ethereal network protocol analyzer has changed its name to Wireshark for Mac. The name might be new, but the software is the same.

Wireshark's powerful features make it the tool of choice for network troubleshooting, protocol development, and education worldwide.

Wireshark for macOS was written by networking experts around the world, and is an example of the power of open source. The app is used by network professionals around the world for analysis, troubleshooting, software and protocol development and education.

The program has all of the standard features you would expect in a protocol analyzer, and several features not seen in any other product.

Its open source license allows talented experts in the networking community to add enhancements.

Features
  • Packet Analysis: It captures data packets from a network in real-time or from saved capture files for in-depth analysis.
  • Deep Inspection: Users can inspect hundreds of protocols, including Ethernet, IP, TCP, HTTP, DNS, and more, to diagnose network issues or investigate security incidents.
  • Filtering: Advanced filtering capabilities allow users to sift through large volumes of data to focus on specific packets or protocols.
  • Protocol Decoding: The app decodes packet contents into human-readable formats, aiding in understanding network communication.
  • VoIP Analysis: Support for VoIP protocols enables analysis of voice and video communications.
  • Exporting: Captured data can be exported to various file formats for further analysis or sharing.
  • Extensibility: It offers a rich ecosystem of plugins and scripts for extending functionality.

New and Updated Capture File Support:

Plugin Development Changes:
- On UN*X systems (excluding macOS when running from an app bundle, as with the official installer) extcap binaries are now searched for under the libexec directory by default, e.g., /usr/libexec/wireshark/extcap instead of /usr/lib64/wireshark/extcap or similar. This is the customary place for helper binaries, which as opposed to libraries do not need multiarch support. The location can be overridden via the environment variable WIRESHARK_EXTCAP_DIR. The extcap binaries shipped with Wireshark are installed in the new location, but third party extcaps may need packaging changes. This change was effective in version 4.6.0, but was not explicitly noted in the release notes previously. Note that some distributions do not use a libexec directory, such as Alpine Linux, which does not have multilib support. On such systems extcap binaries should be in the same location as before.
