SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers building macOS apps often struggle to correctly implement security-conscious system integrations, risking sandbox violations, App Store rejections, and maintenance complexity.

Core Features & Use Cases

  • Comprehensive guidance on sandboxing, entitlements, security-scoped access, and user data protections
  • Guidance for app extensions, Finder integration, XPC services, and system extension patterns
  • Patterns for Menu Bar apps, status items, and background execution to improve user experience and reliability
  • Use Case: Plan a compliant macOS app that runs in the background, offers a menu bar utility, and safely accesses user-selected files

Quick Start

Start by outlining your app's required capabilities and map them to sandboxing, extensions, and menu bar patterns.

Frequently Asked Questions about macos-capabilities

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

FAQPage Schema
How do I configure macOS app sandboxing and entitlements for secure file access?▼

macOS app sandboxing requires declaring specific entitlements in your property list to restrict access, while security-scoped bookmarks allow your app to securely access user-selected files without violating sandbox boundaries.

What are the best practices for building macOS menu bar utility apps?▼

Building macOS menu bar apps requires using status items to display persistent icons and menus, enabling background execution without a dock icon, and following system integration patterns for reliable user experience.

How do I implement app extensions and XPC services for macOS system integration?▼

macOS app extensions and XPC services require defining extension target types and establishing interprocess communication channels, enabling Finder integration, background tasks, and secure system extension patterns.

Why does my macOS app get rejected from the App Store for sandbox violations?▼

Your macOS app gets rejected for sandbox violations when it accesses system resources without declaring the correct entitlements or attempts unrestricted file access, violating App Store security requirements and sandbox boundaries.

Can I run background execution tasks in a sandboxed macOS app?▼

Yes, you can run background execution tasks in a sandboxed macOS app by using background execution patterns and entitlements, ensuring your app respects sandboxing constraints while maintaining reliable system integration.

Do I need XPC services to communicate between my macOS app and its extensions?▼

You need XPC services to establish secure interprocess communication between your macOS app and its extensions, enabling system extension patterns that respect sandboxing boundaries and maintain secure data access.
