+### macOS "too many open files" error
+
+If you encounter the "too many open files" error when running the application on macOS:
+
+```
+failed to create fsnotify watcher: too many open files
+```
+
+This is related to system limits on file system watchers. The kind configuration has been updated to handle this, but if you still encounter issues:
+
+1. Restart your Kind cluster with the updated configuration:
+   ```bash
+   kind delete cluster --name bakery-ia-local
+   kind create cluster --config kind-config.yaml --name bakery-ia-local
+   ```
+
+2. If needed, you can also increase the macOS system limits (though this shouldn't be necessary with the updated kind configuration):
+   ```bash
+   # Check current limits
+   sysctl kern.maxfiles kern.maxfilesperproc
+   
+   # These are usually set high enough by default, but if needed:
+   # sudo sysctl -w kern.maxfiles=65536
+   # sudo sysctl -w kern.maxfilesperproc=65536
+   ```
