+
+    IMPORTANT: CoreAudio Driver Installation Required
+    --------------------------------------------------
+    The driver bundle has been installed to the Nix store, but macOS requires
+    it to be in the system location. To complete the installation, run:
+
+      sudo cp -R $out/Library/Audio/Plug-Ins/HAL/roc_vad.driver \\
+                 /Library/Audio/Plug-Ins/HAL/
+
+    After copying, restart coreaudiod:
+
+      sudo killall coreaudiod
+
+    To uninstall the driver later:
+
+      sudo rm -rf /Library/Audio/Plug-Ins/HAL/roc_vad.driver
+      sudo killall coreaudiod
