NetCheck
NetCheck is a macOS menu bar utility that monitors real internet connectivity and alerts you when your connection drops or recovers.
What is NetCheck?
NetCheck is a native Mac utility for monitoring whether your internet connection is actually working, not just whether Wi‑Fi is connected. It lives in the menu bar and uses lightweight connection checks to confirm online status, helping users spot cases where a Mac shows network bars but the wider internet is unavailable. The app is designed for people who want quick visibility into outages, unstable connections, and response time without opening a larger network tool. It can show a simple status indicator, notify you when connectivity changes, and provide more detail about where a failure is happening in the network path. Pro features add tools such as network history, speed testing, custom probe endpoints, and automation support for users who want deeper monitoring on macOS.

Safety overview
Status: Safe
NetCheck performs network checks as part of its normal purpose and may run in the background from the menu bar or at login so it can watch for outages. That behavior is expected for a connectivity monitor. It may display network-related details such as connection status, latency, VPN state, or ISP information, so keep that in mind if you share your screen. If you no longer want ongoing monitoring or login startup, you can disable or remove the app without affecting macOS itself.
Recommendation: Keep NetCheck if you want a lightweight way to watch internet availability from the menu bar and get outage alerts. If you do not use connection monitoring, login startup, or Pro network tools, you can remove it with little impact beyond losing those features.
