WhatA lightweight system tray app that continuously monitors macOS developer-critical configs (DNS, ports, keychain, network settings) and alerts/auto-fixes when OS updates or system services silently break them.
SignalDevelopers are reporting a pattern of macOS silently breaking multiple developer workflows — ScreenTime hijacking port 8080 and corrupting apt-get downloads, port 5000 being occupied, keychain access failures, Safari cookie management breaking — creating death-by-a-thousand-papercuts that's driving people off the platform entirely.
Why NowApple is shipping increasingly aggressive system services (ScreenTime, mDNSResponder changes, privacy controls) that conflict with developer tooling, and each macOS release introduces new silent breakages with no migration path or documentation.
Market8-10M professional macOS developers, $8-15/mo subscription. No direct competitor — existing tools like Homebrew or DevUtils solve different problems. The gap is that nobody monitors the OS-level config drift that breaks dev environments.
MoatBuilding the comprehensive database of known macOS version-specific breakages and their fixes creates a compounding knowledge advantage — each new OS release adds to the moat as the tool accumulates fix patterns faster than any new entrant.
