Meaning

Open System Settings → Privacy & Security → Automation, expand the host app and enable the target app (System Events, Finder, Safari). If no prompt appears, reset: tccutil reset AppleEvents. Sandboxed/hardened apps need the com.apple.security.automation.apple-events entitlement.

Common causes

  • Automation permission not granted
  • Previously denied prompt
  • Host app re-signed
  • Missing entitlement for hardened builds
  • Running as a LaunchDaemon without GUI session

⚡ Quick fix

  1. Grant in Automation settings
  2. tccutil reset AppleEvents and rerun to get the prompt again
  3. Add the Apple Events entitlement and NSAppleEventsUsageDescription

Detailed fix by platform

macOS

  1. tccutil reset AppleEvents then run the script from the app that needs permission

How to diagnose

  2. Prompt — Shown?
  3. Entitlement — Present?
