SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? macOS security layers like Gatekeeper, codesigning, TCC privacy controls, and SIP can silently reject or kill agent scripts, .app launches, and automation actions, leaving you with cryptic crashes and failed machine operations. ## Core Features & Use Cases - Security Layer Diagnosis: Maps Gatekeeper, codesign, TCC, SIP, sandbox, and Launch Services blocks to their observable symptoms so you can identify which layer rejected an action. - Desktop .app Build Protocol: Provides the xattr quarantine removal and ad-hoc codesign commands needed after building standalone apps like Worker Hub. - Console Crash Interpretation: Explains how to read .ips crash reports for processes like WorkerHubShell, node, and railway, including SIGTRAP/EXC_BREAKPOINT causes. - Use Case: Your Desktop app shows "app is damaged" or crashes on launch with EXC_BREAKPOINT in Console. Use this Skill to check quarantine attributes, re-sign the bundle, and rebuild from the current Swift sources. ## Quick Start Ask the agent to diagnose why your Desktop .app was blocked or crashed on launch and follow the re-signing protocol.

Frequently Asked Questions about hub-pro-mac-security

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix "app is damaged" error on macOS?▼

The "app is damaged" error comes from Gatekeeper quarantine attributes on unsigned apps. Remove quarantine with xattr -cr on the .app bundle, then re-sign it with codesign --force --deep --sign - to allow launching.

How to read macOS Console crash reports for app launch failures?▼

Crash reports live in ~/Library/Logs/DiagnosticReports as .ips files. SIGTRAP or EXC_BREAKPOINT in a shell run loop usually means an old .app build or double NSApp.run() call, so rebuild from current Swift sources.

Why does my macOS automation script silently fail?▼

Silent script failures are typically caused by missing TCC privacy permissions. Automation needs Accessibility for hotkeys, Full Disk Access for log scanning, and Automation (Apple Events) permission for controlling other apps.

What is the difference between Gatekeeper and SIP on macOS?▼

Gatekeeper verifies app signatures and quarantine status before allowing apps to open, while SIP (System Integrity Protection) blocks modifications to protected system files, returning "Operation not permitted" errors.

Can Cursor sandbox block network requests from scripts?▼

Yes, the Cursor sandbox can limit network and shell access, causing empty curl responses or rejected tool calls. Request elevated sandbox permissions like full_network only when the workflow genuinely requires them.
