Network Radar 3.2 Brings a macOS Tahoe Redesign and SSH Update

Witt Software released Network Radar 3.2 on 7 October 2025, updating the Mac network scanner for macOS 26 Tahoe. The release brings the interface in line with Apple's new design language, adds support for the latest version of SSH, refreshes the built-in services and MAC address databases, and raises the minimum system requirement. It is aimed at anyone who needs to see what is on a network, from computing students learning about networks to people looking after a shared house or a small lab.

What's new in Network Radar 3.2

According to the Mac App Store release notes, version 3.2 contains the following changes.

A redesign for macOS Tahoe

The interface now uses new controls introduced in macOS 26 Tahoe, including Liquid Glass buttons in the file preview, among other visual updates. The app icon has also been redrawn to match Tahoe's style, so Network Radar sits naturally alongside Apple's own apps in the Dock and Launchpad. The scroll bar in the filter bar is now hidden, which tidies up one of the most-used parts of the window.

Support for the latest SSH

Network Radar lets you connect to a device by double-clicking it, and SSH is one of the main ways to do that for servers, Raspberry Pis and network hardware. Version 3.2 adds support for the latest version of SSH, which helps when connecting to recently updated machines.

Updated device databases

The app identifies devices partly by looking up the manufacturer from a MAC address and recognising the services a device offers. Both of these databases have been updated, so newer hardware is more likely to be named correctly in scan results.

Fixes and requirements

The release also fixes a problem where entering a licence code might not work under macOS 26, and it moves the minimum supported system from macOS 12 to macOS 13.5.

Earlier in 2025

Version 3.1.1, released in May 2025, made smaller interface refinements and also updated the services and MAC address databases.

What Network Radar does

For readers new to the app, Network Radar scans your local network and lists the devices it finds with details such as IP address, hostname, manufacturer and open services. You can name devices, give them icons and sort them into folders, scan custom IP ranges, and run common network tools with a click. It can monitor devices and notify you when something changes, browse Bonjour (mDNS) services, and use simple rules and actions to automate responses. Results can be exported as XML, CSV, TXT or PDF.

Why it matters for students

• Networking and cyber security modules. Seeing real devices, their open ports and services on a network you own is a clear way to connect lecture theory about IP addressing, DNS and service discovery to practice.
• Raspberry Pi and IoT projects. Finding a headless Pi or microcontroller's IP address is a common stumbling block. A quick scan shows it, and the improved SSH support makes connecting to it straightforward.
• Lab reports and documentation. Exporting a device list to CSV or PDF gives you evidence for a practical write-up or a network design assignment.
• Shared student housing. Monitoring and change notifications help you spot an unfamiliar device joining a home network you manage, or confirm that a printer or smart speaker is still online.

As with any scanning tool, only scan networks you own or have permission to test; university networks usually have policies about this.

Requirements and upgrade details

• Network Radar 3.2 requires macOS 13.5 or later.
• It is sold on the Mac App Store, and version 3.2 was delivered to existing owners as a standard App Store update.
• More information is available on the Witt Software website.
