Ho un macbook pro del 2011, ssd e 16GB di ram (per ora è senza batteria, si è gonfiata l'originale e l'ho tolta).
Il mio problema è che puntualmente dopo 4 ore di utilizzo (lo so bene perchè ci lavoro) il mac si rallenta tantissimo e noto che il kernel_task schizza a valori altissimi.
La batteria l'ho tolta a settembre 2016 e ho poi fatto una installazione di sierra quando uscito. Non mi ricordo quando è iniziato il problema, ma sicuramente dopo l'installazione di sierra.
