Someone Was Here

What makes it different

Someone (else) was here. The Mac app takes a photo of anyone who uses your Mac while you're away and sends it to your phone — when someone sits down after the Mac has been idle, tries the lock screen, or unlocks it.

A second later there's a photo on your phone, through the free iPhone app included with the Mac app. The Mac app itself is free on the Mac App Store; instant alerts to your phone are a $4.99 one-time purchase.

Someone Was Here launched on Hacker News on 9 November 2026 — a small, single-purpose utility for a specific worry: who touched my Mac while I was gone?
