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, 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 showing the signer, requested access, internet reachability, packaged contents, and signals to review. 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. • Executable hash lookup shows SHA-256, SHA-1, and MD5 hashes for target app executables, with quick copying and one-click VirusTotal lookup links. • 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. • Static analysis: before launch, finds domains and URLs that may indicate ads, telemetry, or analytics, plus private framework links and symbols, URL schemes, associated domains, keychain groups, App Groups, and entitlements. Reports stay readable. Important findings appear at the top, good signs are clear, and descriptions expand for detail. Large files load progressively 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 Quick Look and the main report view. Reorder sections and hide what 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 software is safe. It gives practical context before trust: identity, permissions, isolation, bundled code, installer contents, network access, and unusual technical signals.

- Added static analysis that finds domains and URLs embedded in an app before you open it - Added configurable limits for advanced component rows and other network references - Made the collapsed report view more compact
