NetCheck is a lightweight network monitoring utility for macOS that confirms your Mac actually has internet access, not just a local Wi-Fi connection. Unlike the standard Wi-Fi indicator, it runs a network probe and shows a single color-coded dot in the menu bar — green when truly connected, grey when not. When a connection fails, a network path diagram shows exactly where the problem is: the Mac, the router, or the ISP. Free features include a response time meter, automatic ISP identification, VPN connection detection, instant notifications on drop/restore, a customizable polling interval (5 seconds to 5 minutes), and launch at login. No dock icon, no application switcher entry. NetCheck Pro ($9.99, one-time, no subscription) adds Network History with a 0-100 reliability score, custom probe endpoints, CSV export, a built-in speed test, iPhone outage alerts, and Shortcuts integration for automation. Built for anyone who needs constant awareness of connection stability during remote work, video calls, or large file transfers — a persistent, low-resource background utility that stays out of the way.
