NetFluss
NetFluss is a macOS menu bar network monitor that shows live upload and download activity, app bandwidth usage, and connection tools.
What is NetFluss?
NetFluss is a native macOS network utility for monitoring live internet activity from the menu bar. It helps users watch current upload and download rates, identify which apps are using the most bandwidth, and review traffic statistics over time. The app also includes tools for managing Wi‑Fi connections, running speed tests, and viewing connection details without opening a large desktop dashboard. Advanced users can connect it to supported local network devices such as UniFi and OpenWrt to compare router and Mac traffic in one place. NetFluss is designed for people who want quick visibility into network performance and data usage on a Mac, especially while troubleshooting slow connections, background transfers, or unusual traffic.

Safety overview
Status: Mostly safe
NetFluss is a legitimate notarized macOS utility for network monitoring and connection management. Some features may request access related to networking, local network devices, Wi‑Fi details, or location-based system information because macOS uses those permissions to expose network details. If you use router monitoring or VPN features, the app may handle connection credentials and network configuration, so keep only the features you need enabled and review any imported VPN profiles before using them.
Recommendation: Keep NetFluss if you use it to watch bandwidth, troubleshoot network issues, manage Wi‑Fi, or connect VPN profiles from the menu bar. If you no longer use those tools, you can remove it without affecting macOS, though you may also want to delete its saved settings or caches afterward if you want a fuller cleanup.
