Shipping Global Keyboard Shortcuts on macOS Sandbox: The Part Apple Doesn't Document

A Mac menu bar app can capture global shortcuts with a CGEvent tap after Input Monitoring permission is granted.

But in the macOS App Sandbox, CGEvent.post() cannot inject synthetic keystrokes, so the events fail silently.

The practical workaround is to copy the target text to the clipboard and trigger Paste through System Events with AppleScript.

This pattern lets global text-expansion tools work within Mac App Store sandbox restrictions.
