Buongiorno a tutti,
mi rivolgo a voi esperti per un problema al mio macBook nella fase di spegnimento.
Sono possessore di un macBook pro 13" (metà 2012) con ssd da 500 Gb e 8 Gb di ram.
Quando sei mesi fa ho installato la ssd il mac di accendeva e spegneva in pochissimi secondi.
Adesso nella fase di spegnimento la macchina impiega più di 40" ma nella accensione rimane sempre una scheggia.
Ho resettato la pram, smc ma nulla da fare.
Ho quindi eseguito il log nello spegnimento e questo è il risultato:

non sono in grado di risolvere il problema.
penso mi sapreste senz'altro dare qualche dritta.
Vi ringrazio in anticipo per la vostra pazienza e professionalità.
