DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.181

sandbox.allowAppleEvents Setting (macOS)

What

A new macOS-only sandbox setting that permits sandboxed commands to send Apple Events — required for open, osascript, and browser-based auth flows that open URLs.

Usage
// In user or managed settings (not project settings)
{
  "sandbox": {
    "allowAppleEvents": true
  }
}
Details
  • Only honored from user, managed/policy, or CLI --settings settings. Project settings (.claude/settings.json and .claude/settings.local.json) are explicitly ignored.
  • Security warning: Enabling this removes code-execution isolation. Sandboxed commands can launch other applications unsandboxed with no user prompt, and can script running apps (e.g. Terminal) subject to the user's per-app TCC automation consent.
  • Default: false.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
