# sing-box Engine Binary

Place the signed macOS `sing-box` binary here:

```text
Engines/sing-box/sing-box
```

For `XRAY`, `TUIC`, and `HYSTERIA2`, the app writes the backend config to:

```text
~/Library/Application Support/Flux/<TRANSPORT>/sing-box-<transport>.json
```

Then it starts:

```sh
sing-box run -c <generated-config.json>
```
