Hi there, So I've been using my Macbook for years now, and I started to use my Macbook as a desktop more and more. So I decided to get a Mac Mini instead, it looks a bit cleaner on the desk, and it's works better as a desktop in my opinion. I was very happy with it at first, it's not the fastest, but it get things gone. I have built in an SSD, so it is very snappy now. My idea was to never shut it down, but to keep it in sleep mode since it's such a pleasure to just tap your keyboard, and the Mac would unlock itself by recognising your Apple Watch. Unfortunately this is not working all the time... Once I start up my Mac, and I want to make it sleep, I just go to the Apple menu and choose for it to go to sleep, this works fine at first. When I wake my Mac, and after a few hours I want to make it sleep again, it doesn't want to sleep at all. It keeps waking up each time I tell it to sleep. Even after waiting for an hour, it won't go to sleep at all. The energy monitor says there is no app that prevents sleep, and pmset -g assertions says there is nothing preventing sleep as well. (Except for some situations where it says Addressbook sync or something). I even bought Wimoweh to see what's going on, and when it wakes up immediately after I want it to sleep, it shows this: It seems like com.apple.powermanagement.darkwakelinger is the one who is causing it to keep it awake all the time. DisplayOff is not always showing in there though, it's mostly darkwakelinger. I even turned off 'Turn off sleep mode for network access' (Or something like that, I have it in Dutch) from the energy settings, and I thought this was such a handy feature. I hope someone can help me out with this, because this is really frustrating, and it's really taking away a great feature I loved. Some help would be really appreciated!
