dontallow - Auto-dismiss macOS local network permission prompts

Show HN: Auto Dismiss Mac OS "Allow <app> to find devices on local networks?"

Tired of macOS Sequoia repeatedly asking whether apps like Google Chrome can find devices on your local network? dontallow is a tiny Swift agent that automatically presses "Don't Allow" within a fraction of a second, every time. It runs with zero idle CPU, survives reboots, and installs easily via Homebrew. The tool targets a real annoyance: Chromium browsers and apps with versioned install paths keep triggering fresh prompts, cluttering Privacy settings with orphaned entries. dontallow includes pause windows, an allowlist for apps that genuinely need LAN access, and a rules decoder to inspect what each Privacy row really is. One file, no dependencies.
