-**Fix 3: Check embedded gateway**
-Ensure the gateway relay was properly bundled. Run [`./scripts/package-mac-app.sh`](https://github.com/clawdbot/clawdbot/blob/main/scripts/package-mac-app.sh) and ensure Node is available (the script downloads a bundled runtime by default).
+**Fix 3: Check the CLI install**
+Ensure the global `clawdbot` CLI is installed and matches the app version:
+```bash
+clawdbot --version
+npm install -g clawdbot@<version>
+```
