Security Growler
Security Growler is a free menu bar utility for macOS that monitors and alerts users to authentication events including SSH logins, FTP connections, VNC sessions, AFP (Apple Filing Protocol) access, and sudo command execution. System administrators and security-conscious users rely on it to detect unauthorized access attempts or to track who is accessing their computer's resources and services. The app integrates with macOS Notification Center and Growl, and can send alerts to iOS devices via Prowl. It is extensible through Python modules, allowing users to add custom monitoring for additional log files or processes.
AI Recommendation
1 suggestionSecurity Growler has not been updated since version 2.3 in the mid-2010s, and there is no native Apple Silicon build. The app continues to run under Rosetta 2 today, but will stop launching entirely when Apple removes Rosetta in macOS 28 (September 2028). Before the deadline, you should migrate to an actively maintained alternative. On modern macOS, the built-in log stream monitoring (via Console.app or `log stream` in Terminal) combined with native security tools provides comparable visibility into SSH, FTP, and sudo events. For users who specifically want a graphical security dashboard, Kolibri for Mac (a native Apple Silicon app) offers real-time process and network monitoring with similar paranoia-level insight. If you have custom Python monitoring scripts, you can migrate them to cron or launchd daemons that continue to work without UI notification. Consider reviewing what specific events you monitor today and whether those gaps are covered by System Settings → Security & Privacy, the native Firewall, or a modern third-party security tool.
