macOS Network Traffic Monitor: Per-App Bandwidth - iNTM

Monitor macOS network traffic in real time, analyze per-app bandwidth usage, review traffic history, and move from suspicious connections to local firewall rules.

  • Monitor macOS network traffic in real time, analyze per-app bandwidth usage, review traffic history, and move from suspicious connections to local firewall rules.
  • See which apps are using your network, how much bandwidth they consume, where connections go, and which requests deserve a local app firewall rule.
  • Quick answer
  • What is a macOS network traffic monitor?
  • A macOS network traffic monitor helps you see live upload and download activity, identify which apps are using bandwidth, inspect remote endpoints, and review usage history. iNTM adds app firewall control so you can move from traffic investigation to local connection rules.
  • Monitor real-time Mac upload and download speed
  • Find which app is using internet bandwidth
  • Review domains, IP addresses, ports, and protocols
  • Create firewall rules after suspicious traffic is found
  • What you can monitor
  • Built for real Mac network visibility
  • Activity Monitor can show broad network numbers. iNTM goes deeper by connecting traffic usage, applications, remote endpoints, history, and app firewall control in one native macOS workflow.
  • Real-time traffic speed
  • Track upload and download speed as it changes, including quick status bar visibility for day-to-day monitoring.
  • Per-app bandwidth usage
  • Identify which Mac apps consume bandwidth and separate normal background traffic from unusual spikes.
  • Traffic history review
  • Review historical network usage by app and time period, then use trends to understand recurring bandwidth drains.
  • Local app firewall control
  • Create firewall rules for apps, domains, IPs, and ports when monitoring reveals a connection you do not want to allow.
  • Workflow
  • From traffic spike to clear action
  • A useful macOS network traffic monitor should help you move from noticing activity to understanding and controlling it.
  • Watch real-time network activity
  • Use live speed and connection views to spot unexpected upload or download activity.
  • Find the app behind the traffic
  • Group usage by application so a vague network spike becomes a specific process you can inspect.
  • Review remote endpoints
  • Check domains, IP addresses, ports, protocols, and connection timing before deciding whether traffic is expected.
  • Apply a local rule when needed
  • Block or restrict unwanted traffic with app-level firewall rules that run locally on your Mac.
  • Comparison
  • Why not just use Activity Monitor?
  • Activity Monitor is useful for a quick system snapshot. iNTM is designed for people who need ongoing network traffic monitoring, per-app investigation, and connection control.
  • Live speed
  • Basic network throughput at system level.
  • Real-time traffic monitoring with app-focused context and status bar visibility.
  • Per-app analysis
  • Limited detail for investigating app bandwidth patterns.
  • Per-app usage, historical trends, and connection details in one workflow.
  • Connection control
  • Observation only.
  • Local firewall rules for apps, domains, IPs, and ports.
  • Privacy posture
  • Local system utility.
  • Traffic metadata and firewall rules are processed locally; packet content is not uploaded.
  • Private by design
  • Network monitoring is sensitive. iNTM is built around local processing so you can inspect traffic without turning your Mac activity into a cloud dashboard.
  • No account is required for core network monitoring.
  • Traffic statistics and connection metadata stay in the local app sandbox.
  • Firewall rules execute locally on your Mac.
  • Packet payloads, passwords, and visited content are not uploaded.
  • Related control
  • Pair traffic monitoring with a Mac app firewall
  • When a traffic spike becomes a suspicious connection, the next step is control. iNTM links monitoring and firewall rules in one workflow.
  • macOS App Firewall
  • Block or allow app connections by application, domain, IP address, and port.

  • macOS network traffic monitor FAQ
  • Can iNTM show network traffic by app?
  • Yes. iNTM is designed to connect traffic usage with applications so you can identify which Mac apps are using bandwidth.
  • How do I see which app is using the internet on my Mac?
  • Use iNTM's per-app traffic view to group live and historical network activity by application, then inspect the remote domains, IP addresses, ports, and protocols behind that traffic.
  • Can it help find unusual background traffic?
  • Yes. Real-time speed, per-app usage, connection details, and history make it easier to investigate unexpected traffic spikes.
  • Can I block unwanted network traffic after I find it?
  • Yes. iNTM includes local app firewall controls, so you can monitor traffic and create rules for apps, domains, IPs, and ports.
  • Is iNTM only a network speed monitor?
  • No. iNTM combines real-time network speed, per-app bandwidth analytics, connection inspection, traffic history, and local app firewall rules.
  • Does iNTM upload packet content?
  • No. Traffic statistics, connection metadata, and firewall rules are processed locally. Packet payloads, passwords, and visited content are not uploaded.
