CommunityImplement secure macOS IPC with XPC services
System Documentation
What problem does it solve?
This Skill solves the challenge of implementing secure, reliable inter-process communication (IPC) on macOS, which is required for privilege separation, cross-process data sharing, and signaling between app components, helper tools, and system daemons without introducing security vulnerabilities.
Core Features & Use Cases
- XPC Service Implementation: Full support for NSXPCConnection, NSXPCInterface, and @objc protocol setup for Mach-based XPC services, including privilege separation with SMJobBless for root helper tools.
- Cross-Process State Sharing: App Groups integration for shared NSUserDefaults and file containers between apps and XPC services, plus DistributedNotificationCenter for lightweight cross-process signaling.
- Use Case: Build a sandboxed macOS app that delegates privileged operations (like system configuration changes) to a separate root helper tool via XPC, while sharing state between the app and helper via App Groups.
Quick Start
Use the macos-ipc-xpc skill to implement a secure XPC service for your sandboxed macOS app that handles privileged operations, with proper caller audit token validation and shared App Group state synchronization.
