My iMac (27 pollici, Fine 2012) si sveglia in modo casuale, fino a 9 volte al giorno. Sto utilizzando El Capitan 10.11.3 (15D21) .
Un syslog | grep -i "Wake reason" mostra le seguenti molte volte:
Apr 5 00:02:50 Nikolajs-iMac kernel[0] <Notice>: Wake reason: EC.SleepTimer (SleepTimer)
Apr 5 00:02:52 Nikolajs-iMac kernel[0] <Notice>: [HID] [ATC] AppleDeviceManagementHIDEventService::processWakeReason Wake reason: Host (0x01)

Apr 6 22:31:21 Nikolajs-iMac kernel[0] <Notice>: [HID] [ATC] AppleDeviceManagementHIDEventService::processWakeReason Wake reason: Host (0x01)
Non ci sono dispositivi USB collegati, né dispositivi Bluetooth, tranne tastiera e mouse.
I motivi più ovvi, power nap e wake on lan , non sono attivati. Ho già provato ad attivarli ma non è stato d'aiuto. Cos'altro potrebbe essere?
Ho cercato su Google le risposte per un lungo periodo di tempo, molte volte, ma non sono riuscito a trovare alcuna soluzione. Il problema persiste già per almeno due versioni principali di OSX.
Grazie mille!

Aggiornamento 2: sono riuscito a inserire il pmset -g assertions subito dopo che l'imac si è svegliato la scorsa notte. Ecco l'output:
