+# iMessage
+
+## Overview
+
+The iMessage integration is a legacy external CLI tool that connects OpenClaw to Apple Messages on macOS.
+
+**Note:** BlueBubbles is recommended for new setups. The `imsg` channel may be removed in future releases.
+
+## Setup Requirements
+
+The basic configuration involves three steps:
+
+1. Ensure Messages is signed in
+2. Install the `imsg` tool via Homebrew
+3. Configure two paths in OpenClaw's settings
+
+The system requires:
+- Full Disk Access for OpenClaw + `imsg`
+- Automation permissions for sending messages
+
+## Account Configuration Options
+
+Users can set up iMessage in single-account or multi-account modes. For isolated bot identities, the documentation describes creating a dedicated Apple ID and separate macOS user account, with Remote Login enabled for SSH access.
+
+## Remote Setup
+
+The integration supports running `imsg` on a remote Mac via SSH, with automatic attachment retrieval through SCP.
+
+### Tailscale Example Architecture
+
+A Linux Gateway connects to a Mac over a private network, enabling iMessage functionality without direct macOS hosting.
+
+## Access Control
+
+Two policy types manage permissions:
+
+- **pairing** (default for DMs): Generates codes for unknown senders
+- **allowlist**: Restricts group participation
+
+The system uses mention patterns since iMessage lacks native mention metadata.
+
+## Message Handling
+
+- Messages are chunked to a configurable character limit (default 4000)
+- Optional newline-based chunking splits on paragraph boundaries
+- Group sessions receive isolated identifiers
+- DM sessions share the agent's main context
