La directory / core di OSX Mountain Lion è importante? È vuoto sulla mia macchina e lo è da un po 'di tempo, quindi stavo pensando di cancellarlo, ma non vorrei fare confusione.
La directory / core è solitamente nascosta e viene utilizzata per le informazioni di debug dopo gli arresti anomali. Qualsiasi file all'interno è probabilmente sicuro da eliminare, ma in genere è una cattiva idea rimuovere qualsiasi directory di sistema. È normale e dovrebbe essere presente su tutte le installazioni di OS X.
Suggerisco di non eliminare alcuna cartella Unix sull'unità se non si desidera reinstallare il sistema operativo. Potrebbe essere che qualsiasi funzione che tenta di accedervi lo creerà se non ci sarà, ma potrebbe anche finire in problemi ed errori.
La directory si riempie di core dump dai programmi che si bloccano. Puoi cancellare liberamente qualsiasi file lì. Il mio riempie regolarmente fino a decine di gigabyte e non viene mai eliminato dal sistema operativo Apple. Il problema è particolarmente grave se hai un sacco di file strani che la ricerca full-text di Apple tenta di indicizzare, a volte l'indicizzatore si blocca.
