App Trust Preview helps you understand Mac software before you open it. Drop in an app bundle, installer package, disk image, binary executable, or script. Choose a file from disk, inspect from Finder with Quick Look, or export reports from the command line. App Trust Preview turns macOS security metadata into a readable trust report: who signed it, what access it may ask for, whether it can reach the internet, what is packaged inside it, and which signals deserve a closer look. What App Trust Preview checks: • Identity and signing: signing status, Team ID, bundle ID, version, distribution type, certificate chain, signing timestamp, and whether the signature still matches the file on disk. • Apple safety signals: Developer ID or Mac App Store distribution, notarization indicators, certificate revocation status, quarantine flag, sandbox status, hardened runtime status, and outgoing internet access declarations. • Privacy access: camera, microphone, screen recording, accessibility, contacts, calendars, reminders, photos, location, Bluetooth, local network, speech recognition, Apple Events, 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 can show saved decisions such as allowed, denied, limited, add-only, or not decided yet. • Internet trust signal: sandboxed apps without a network entitlement are shown as unable to make direct internet connections. If software is not sandboxed, App Trust Preview explains why that entitlement alone does not restrict it. • Inside apps and disk images: helper tools, login items, XPC services, extensions, frameworks, plug-ins, dynamic libraries, nested apps, architectures, minimum macOS target, and bundle size. • Installer packages: package components, install locations, authorization requirements, install scripts, and files contained in the package when available. • Binary executables and scripts: Mach-O metadata, platform, minimum OS, SDK, linked libraries, runtime search paths, code signature data, and readable script source previews. • Helper safety: whether internal executables are signed, unsigned, invalidly signed, sandboxed, or able to do more than the main app. • Technology detection: Electron, Chromium or CEF, Firefox or Gecko, ToDesktop, Tauri or Wry, WebKit, Qt WebEngine, SwiftUI, React Native, Flutter, Unity, Unreal Engine, Godot, Wine or CrossOver, Java, .NET, Python, Node.js, Mac Catalyst, and iOS apps running on Mac. • Private API and technical indicators: Apple private framework links, private-looking symbols, URL schemes, associated domains, keychain groups, App Groups, and recognized entitlements. Reports are readable first. Important findings appear at the top, good signs are shown as good signs, and descriptions expand when you want more detail. Large files load progressively, so available information appears while slower checks continue. Quick Look lets you inspect supported files directly from Finder. The full app adds deeper interaction, reload, and export. Use Settings to configure the Quick Look preview and the main report view. Reorder sections and hide sections you do not need. Export reports as PDF, PNG image, JSON, or plain text for records, support notes, security review, or comparisons. For automation, App Trust Preview includes a command line interface that exports reports for a given app, package, disk image, executable, or script. Use it in workflows, shell scripts, security review pipelines, or external AI analysis. App Trust Preview runs its analysis locally on your Mac. It does not upload inspected software to a server. App Trust Preview is not a malware scanner and cannot prove that software is safe. It gives practical context before trusting software: identity, permissions, isolation, bundled code, installer contents, network access, and unusual technical signals.
