App Trust Preview helps you understand a Mac app before you open it. Drop in an app bundle, choose one from disk, or press Space in Finder with the Quick Look extension. App Trust Preview turns macOS security metadata into a readable trust report: who signed the app, what access it may ask for, whether it can reach the internet, what is packaged inside it, and which signals are worth a closer look. What App Trust Preview checks: - Developer identity: signing status, Team ID, bundle ID, version, distribution type, certificate chain, signing timestamp, and whether the signature still matches the app on disk. - Apple safety signals: Developer ID or Mac App Store distribution, notarization indicators, certificate revocation status, quarantine flag, App Sandbox status, Hardened Runtime status, and whether the app declares outgoing internet access. - Privacy access: camera, microphone, screen recording, accessibility, contacts, calendars, reminders, photos, location, Bluetooth, local network, speech recognition, motion, HomeKit, tracking, Apple Events, system administration, and other sensitive access declared through purpose strings or entitlements. - Current permission decisions: when macOS allows the local privacy database to be read, App Trust Preview shows whether a selected app already has a saved decision such as allowed, denied, limited, add-only, or not decided yet. Rows can take you to the matching Privacy & Security setting. - Internet trust signal: sandboxed apps without a network entitlement are clearly shown as unable to make direct internet connections. If an app is not sandboxed, App Trust Preview explains why that entitlement alone does not restrict it. - Inside the app: helper tools, login items, XPC services, app extensions, frameworks, plugins, dynamic libraries, nested apps, architectures, minimum macOS target, bundle size, and the newest modified file inside the bundle. - Helper safety: whether internal executables are signed, unsigned, invalidly signed, sandboxed, or able to do more than the main app. - App technology detection: Electron, Chromium or CEF, Firefox/Gecko, ToDesktop, Tauri/Wry, Capacitor, Cordova, WebKit, Qt WebEngine, AppKit, SwiftUI, React Native, Flutter, Unity, Unreal Engine, Godot, Wine/CrossOver, JetBrains Runtime, Java, .NET/Mono/CoreCLR, Python, Node.js, Mac Catalyst, and iOS apps running on Mac. - Private API indicators: best-effort detection of Apple private framework links and private-looking symbols or selectors, with clear wording when the evidence is strong or only a static string match. - Technical details: Mach-O platform, minimum OS, SDK, linked libraries, runtime search paths, code signature hashes, provisioning profile data, URL schemes, document types, associated domains, iCloud containers, keychain groups, App Groups, App Transport Security, and recognized entitlements. Reports are designed to be readable first. Important findings are shown at the top, good signs are shown as good signs, and descriptions can be expanded only when you want them. Large apps load progressively, so available information appears immediately while slower checks continue. Quick Look support lets you inspect an app directly from Finder without opening the main window. The full app adds deeper interaction, reload, copyable fields, System Settings shortcuts, and export. Export reports as PDF, PNG image, JSON, or plain text for records, support notes, security review, or before/after comparisons. App Trust Preview runs its analysis locally on your Mac. It does not upload the app you inspect to a server. Some checks depend on what macOS allows a sandboxed app to read, and certificate revocation answers may come from macOS trust services. App Trust Preview is not a malware scanner and cannot prove that software is safe. It gives you practical context before trusting an app: identity, permissions, isolation, bundled code, network access, and unusual technical signals.
