Overview

XPC (Cross-Process Communication) is Apple's framework for secure communication between separate processes on macOS. It provides a lightweight, low-overhead mechanism for splitting applications into multiple processes for security isolation and reliability. XPC is commonly used for privilege separation, sandboxing, and building modular applications where different components run in isolated processes.
