+## Troubleshooting
+
+#### macOS OpenMP runtime conflict
+On macOS, especially on Intel Macs, `faster_whisper`/`ctranslate2` can conflict with OpenMP runtimes loaded by other Python packages. If the server aborts with a duplicate OpenMP runtime error, run the server with `KMP_DUPLICATE_LIB_OK=TRUE`:
+
+```bash
+KMP_DUPLICATE_LIB_OK=TRUE python3 run_server.py --port 9090 \
+                      --backend faster_whisper \
+                      --max_clients 4 \
+                      --max_connection_time 600 \
+                      --no_single_model
+```
+
+This workaround is intended for local development and testing. For production deployments, prefer using a clean environment that loads only one OpenMP runtime.
