I just purchased a new 2013 iMac a couple days ago and I'm having a problem where it will not stay in sleep mode. I get up from it put it to sleep, it will stay a sleep for 5 - 10 minutes and wake it self up. I have "Wake for network access" and "Enable power nap" off in energy saver. I've tried closing ever program before sleeping, turning my mouse and bluetooth speakers off no difference it will still wake up. Does anyone have any ideas?
