# Someone Was Here: Mac Security Monitoring App A new Mac utility captures photos of unauthorized users and sends instant alerts. - **Source:** [Hacker News: Front Page](https://brifing.si/source/b07aa772-b1a0-4a76-aa18-719c6f9e2dde) - **Published:** 2026-11-09 - **Topic:** [technology](https://brifing.si/c/technology) - **Original article:** - **On Brifing:** https://brifing.si/s/4968e08e-43e5-44ca-8e20-f03ead9b13c8 ## Automated Mac Security Monitoring The Someone Was Here application monitors Mac devices for unauthorized access attempts. It captures a photo of anyone using the computer while the owner is away. The system records the exact time of access, the method of entry, and the total duration of the session to provide a comprehensive security log. ## Facial Recognition Setup Process Users configure the software through a two-minute setup process requiring a few head turns. This allows the application to learn the owner's face, ensuring the system does not trigger false alerts when the primary user returns. The software performs all facial verification locally on the Mac to maintain user privacy standards. ## Instant Mobile Alert System Captured photos are transmitted to the user's iPhone within seconds of an unauthorized access event. While the base Mac and iPhone applications are free, instant push notifications require a one-time purchase of 4.99 dollars. This ensures that owners remain informed about their device status even when they are physically distant from it. ## Stealthy Operation and Integration The software operates discreetly from the menu bar without altering the screen state during an intrusion. It supports multiple notification channels, including iCloud, Pushover, ntfy, Telegram, and webhooks. This flexibility allows users to integrate the security alerts into their existing communication workflows while maintaining a low profile during the monitoring process. ## Ethical Use and Transparency The developer explicitly advises users to inform others if they share their workspace. Because the tool is designed for personal Mac protection, transparency is recommended to avoid privacy conflicts in shared environments. Users should review the provided privacy policy to understand how their data is handled during the monitoring and notification process. ## Technical Requirements and Availability The application is currently available for download on the Mac App Store. To receive the photo alerts, users must also install the companion iPhone application. The system relies on the user's existing iCloud infrastructure to sync data between the Mac and the mobile device, ensuring a seamless and relatively secure transfer of images. ## Mechanism of Access Detection The software triggers a capture event when the Mac has been idle, when someone attempts to bypass the lock screen, or when the device is successfully unlocked. By logging these specific triggers, the tool provides context on how the intruder gained access, helping the owner understand the nature of the security breach. ## Security Utility Market Context This tool addresses the growing demand for personal hardware security in shared or public workspaces. By combining local facial recognition with remote notification capabilities, it offers a lightweight alternative to enterprise-grade surveillance software. It serves as a practical solution for individuals seeking to deter unauthorized use of their personal computing equipment. ## Sources covering this story - https://someonewashere.app/ — --- _Summary written by Brifing from the original reporting.
