Il mio MacBook Air (di pochi mesi) si sveglia in modo casuale dal sonno circa 3 ore dopo la chiusura del coperchio. Il motivo della veglia è dato come EC.LidOpen, ma in realtà il coperchio rimane chiuso. Il mac sembra tornare immediatamente a dormire. Non sto riscontrando alcuna conseguenza negativa, ma volevo essere sicuro di non dovermi preoccupare del malware.
Ad esempio (questo si verifica ogni notte)
log show --style syslog | fgrep "Wake reason"
2017-03-18 01:33:44.916848+0100 localhost kernel[0]: (AppleACPIPlatform) Wake reason: EC.SleepTimer (SleepTimer)
2017-03-18 04:33:58.836023+0100 localhost kernel[0]: (AppleACPIPlatform) Wake reason: EC.LidOpen (User)
EDIT : usando pmset -g log, ho ottenuto più informazioni sui misteriosi risvegli, che sembrano essere causati da mDNSResponder.
