“Someone Was Here” 是一款免费的 Mac 应用，配有免费 iPhone 伴侣应用，可在你离开时检测是否有人使用你的 Mac——在空闲一段时间、尝试锁屏或解锁后——并拍摄他们的照片，记录时间、访问方式和会话时长。它会在快速设置中学习你的面部，不会对你发出提醒。照片会在几秒内通过你自己的 iCloud 或其他服务发送到你的 iPhone，同时屏幕上没有任何变化。当你返回时，Mac 会告诉你谁来过。应用常驻菜单栏，使用摄像头指示灯，照片保存在你的 Mac 上，无需账号，无广告或追踪。即时手机提醒一次性收费 4.99 美元。它旨在保护你自己的 Mac；如果你与他人共用空间，请披露。

一条 Hacker News 的 "Show HN" 帖子介绍了 "Someone Was Here"，这是一款 macOS 菜单栏应用，可在你离开时拍摄使用你 Mac 的任何人，并在识别出不是你的脸时发出警报。它基于 Apple Vision 和本地 Core ML 人脸识别构建，完全在设备端运行，无追踪或广告。远程警报需通过配套的 iPhone/iPad 应用、Pushover、ntfy、Telegram 或 webhook 一次性支付 4.99 美元。开发者灵感来源于前任未经许可访问其 Mac，将其定位为类似家庭安防的审计记录，而非替代锁定机器的方案。该应用还检测锁定屏幕上的活动、空闲唤醒以及无盖的台式 Mac，在识别到机主面部时抑制警报。评论者反应不一：有人觉得它令人不适或不必要（更倾向于使用锁/YubiKey），也有人认为它对共享或家庭电脑有价值。提到了 Objective See 的 DoNotDisturb 等替代方案。开发者强调了沙盒、本地处理、服务器无法访问照片，以及透明的菜单栏显示与摄像头指示灯。

When someone sits down, it takes their photo.

Someone uses your Mac after it's been idle, tries the lock screen, or unlocks it. A second later there's a photo of them, with the time, how they got in, and how long they stayed.

A Mac desktop with the Someone Was Here panel open from its name-tag icon in the menu bar: the latest visit's photo of a man, marked Someone else, with a HELLO sticker reading 2:52 pm, and a list of earlier visits.

When it's you, it stays quiet.

It learns your face in a two-minute setup with a few head turns, and checks every photo right on your Mac. You won't get an alert about yourself.

The Someone Was Here panel open from the menu bar on a visit marked You, with a HELLO sticker reading You were here at 9:03 am, and Recognition: Matched your photos.

Then it tells you.

The photo reaches your iPhone within seconds, in the free Someone Was Here app. Nothing changes on screen while they're at your Mac. When it sees you again, your Mac tells you who came by.

The Someone Was Here iPhone app on its Visits screen: the latest photo, of a man at the Mac, marked Someone else with a HELLO sticker reading 4:05 pm, and earlier visits listed below.

It isn't hiding anything.

It sits in your menu bar where you can see it, and it's made for protecting your own Mac. If you share your space, tell people it's there.
