    Hello,

    Newbie here, It has just come to my attention that my 27" iMac wakes up during the night. It is always put to sleep at night rather than turned off. My parents are staying for the weekend & sleeping in the same room as the imac, & mentioned this morning that screen turned on a couple of times during the night. I looked at the time machine back ups & found it had made 2 during the night.
    Is this normal ?

    Thank you & Happy Christmas to you all

    Phil

    Go into System Preferences and click "Energy Saver". Uncheck "Wake for Network Access" if that is checked, it might be causing your system to randomly wake up during the night.
