+### Local Gateway + Parallels Chrome
+
+You do **not** need a full OpenClaw Gateway or model API key inside a macOS VM
+just to make the VM own Chrome. Run the Gateway and agent locally, then run a
+node host in the VM. Enable the bundled plugin on the VM once so the node
+advertises the Chrome command:
+
+What runs where:
+
+- Gateway host: OpenClaw Gateway, agent workspace, model/API keys, realtime
+  provider, and the Google Meet plugin config.
+- Parallels macOS VM: OpenClaw CLI/node host, Google Chrome, SoX, BlackHole 2ch,
+  and a Chrome profile signed in to Google.
+- Not needed in the VM: Gateway service, agent config, OpenAI/GPT key, or model
+  provider setup.
+
+Install the VM dependencies:
+
+```bash
+brew install blackhole-2ch sox
+```
+
+Reboot the VM after installing BlackHole so macOS exposes `BlackHole 2ch`:
+
+```bash
+sudo reboot
+```
+
+After reboot, verify the VM can see the audio device and SoX commands:
+
+```bash
+system_profiler SPAudioDataType | grep -i BlackHole
+command -v rec play
+```
+
+Install or update OpenClaw in the VM, then enable the bundled plugin there:
+
+```bash
+openclaw plugins enable google-meet
+```
+
+Start the node host in the VM:
+
+```bash
+openclaw node run --host <gateway-host> --port 18789 --display-name parallels-macos
+```
+
+Approve the node from the Gateway host:
+
+```bash
+openclaw devices list
+openclaw devices approve <requestId>
+```
+
+Confirm the Gateway sees the node and that it advertises `googlemeet.chrome`:
+
+```bash
+openclaw nodes status
+```
+
+Route Meet through that node on the Gateway host:
+
+```json5
+{
+  plugins: {
+    entries: {
+      "google-meet": {
+        enabled: true,
+        config: {
+          defaultTransport: "chrome-node",
+          chromeNode: {
+            node: "parallels-macos",
+          },
+        },
+      },
+    },
+  },
+}
+```
+
+Now join normally from the Gateway host:
+
+```bash
+openclaw googlemeet join https://meet.google.com/abc-defg-hij
+```
+
+or ask the agent to use the `google_meet` tool with `transport: "chrome-node"`.
+
+If `chromeNode.node` is omitted, OpenClaw auto-selects only when exactly one
+connected node advertises `googlemeet.chrome`. If several capable nodes are
+connected, set `chromeNode.node` to the node id, display name, or remote IP.
+
+Common failure checks:
+
+- `No connected Google Meet-capable node`: start `openclaw node run` in the VM,
+  approve pairing, and make sure `openclaw plugins enable google-meet` was run
+  in the VM.
+- `BlackHole 2ch audio device not found on the node`: install `blackhole-2ch`
+  in the VM and reboot the VM.
+- Chrome opens but cannot join: sign in to Chrome inside the VM and confirm that
+  profile can join the Meet URL manually.
+- No audio: in Meet, route microphone/speaker through the virtual audio device
+  path used by OpenClaw; use separate virtual devices or Loopback-style routing
+  for clean duplex audio.
