Per impedire a Spotlight di indicizzare l'unità, creare un file di testo in chiaro in TextEdit senza contenuto, solo il titolo di .metadata_never_index e salvarlo sull'esterno.

Non sono sicuro che ciò lo fermerà in questo momento, ma lo impedirà in futuro.
In alternativa, crea Applescript in un'app, per forzare l'espulsione [con i soliti avvertimenti sull'esclusione forzata ...] ... credito al blog MacTipper
