How to install NetworkMonitor on a Mac

  1. Get OpenDMG. It is a free app store for open source Mac apps. Download OpenDMG.
  2. Search for NetworkMonitor and press Get. OpenDMG downloads version 1.31.0 from kevinabouhanna's own GitHub release.
  3. Open it. The download is checked against its SHA-256 fingerprint and its signature is checked on your Mac before it lands in Applications.

Updates to NetworkMonitor show up in OpenDMG and install with one button. No account is needed.

Prefer to do it by hand? The developer's file is on GitHub: NetworkMonitor.dmg (15 MB).

What is new in NetworkMonitor 1.31.0

### Installing

Download **NetworkMonitor.dmg** below, open it, drag NetworkMonitor into
**Applications**, and open it from there.

### Updating

From 1.15 on, NetworkMonitor offers each new version itself: **Check for
Updates…** in its menu, or once a day on its own. Before that, download
the disk image and drag NetworkMonitor into Applications again, choosing
**Replace**. Your settings and usage history stay.

Updating from 1.13 or earlier, macOS asks for Location once more: the app
is now signed with an Apple Developer ID instead of its own certificate,
so macOS sees it as new this one time.

### What's new in 1.31.0

- **Pause ad blocking from the menu bar.** The popover's Ads blocked view says whether ads are blocked, with **Pause** for 1 hour, until tomorrow or on this network, and **Resume**; the menu bar item's right-click menu has the same (#600).
- **Your rules, where you look for them.** **Rules** sits beside Traffic and Blocked in Connections, and beside Overview and the Log in Ads and Trackers: each rule with what it did in the period, a menu to change it, and a bar to add a site. Ad blocking's *Never block* and *Always block* are now **Always Allow** and **Block**, as in Connections (#592, #638).
