So I put my MacBook Air to sleep last night at 00:40 and woke it up again at 09:54. For the entries at 01.41am I was on my iPhone at that point, but my MBA was sleeping.... I'm assuming. The ****** is where I have censored out my name. Any help is appreciated. It looks like it was waking every hour. http://pastebin.com/JEuM7jWP EDIT: Just realising Power Nap is turned on. Maybe this is something to do with it? Wake for Wi-Fi access is turned off.
