dontallow

What is dontallow?

dontallow is a macOS utility that automatically dismisses the system prompt asking whether an app should be allowed to find devices on local networks. It runs as a background launchd agent and presses Don't Allow within a fraction of a second whenever the dialog appears. The tool uses zero CPU while idle and persists across system reboots.

The prompt frequently reappears for certain applications, particularly Chromium-based browsers that copy their executable to temporary folders during updates. This causes macOS to treat each launch as a new app, filling the privacy settings with duplicate entries. dontallow intercepts these requests before they reach the user.

Users can pause automatic dismissal for a set duration, add apps to a whitelist, or manually allow access through System Settings when a feature actually requires local network discovery. The tool logs each action and posts desktop notifications so users can track which apps triggered the prompt.
