iMac randomly wakes from sleep and screen comes on since updating to Sierra

Thanks trevoz.

I had a read through the thread, and seen the advice about running the below Terminal command.

log show --style syslog | fgrep -i sleep | fgrep -v mDNS

I ran it, and here's some information off of it from yesterday and today till I manually woke my iMac (I will point out that when I went to wake my iMac this morning, it was already awake, and its display had turned off, which it is set to do after 10 minutes of no use. So it must have awoken from sleep after I put it to sleep last night and had remained awake).

One thing I haven't tried, is disconnection all the USB devices from my iMac and see if the problem still happens, which I will do later on today.

Here's some information from Terminal, its a bit long, but there was quite a lot of entries in for yesterday and I thought if I could provide a lot of information from yesterday and today, it might help better show the cause.

Here's the information from Terminal:

Also, from Activity Monitor, there is one thing in there that shows Yes in the Preventing Sleep column that seems to always show Yes (a process name called hidd).

And the entry below called mds_stores shows Yes and then goes back to No.

Also, another look in Activity Monitor shows some more entries showing Yes in Preventing Sleep, but the second and third entries down, quickly turn back to No.

Hidd is the daemon responsible for processing human input - keystrokes, mouse/keypad movement, etc.

So if your Mac has seen any input from you within the past several minutes, hidd will be preventing the system from sleeping.

Ok thanks I see. I wasn't sure what the process name was for and with it showing Yes in the Preventing Sleep column I though that might have been the cause for the waking from Sleep when I am not using my iMac.

I haven't used FaceTime. I've never used it since owning a Mac.

I've just loaded up FaceTime and I was logged into it. So I've logged out.

Despite logging out of FaceTime, my Mac has just awoken from sleep now and the screen has come on.

I've had my Mac wake from sleep numerous times since owning one, and from advice given when I first got my Mac and questioned this behaviour, I was told it is normal for a Mac to do this, to perform certain tasks.

But, from what I mentioned above in mind, you could hear the fan, hard drive spin up (but the screen did not come on), and after a short time they would stop and my Mac would go back to sleep.

But what I am seeing now is, my Mac wakes from sleep and the screen comes on, and once its woken up, it stays awake. For example, during last night, my Mac was awoken and when I went to it this morning I could hear that the hard drive and fan was running. So its stayed awake since whatever it was that awoken it.

I had two times this evening where my iMac woke up from sleep, I noted the times down incase I can figure out how to get info from Terminal to whatever it was at that particular time that caused it.

What I will try tonight before I go to bed, is. I'll disconnect all the USB devices plugged into my iMac and see if it still wakes up.

The first paragraph is for the time of the first event this evening that caused my Mac to wake.

My Mac won't let me do this. It mentions "You cannot control your computer if you turn Bluetooth off at this time".

I used to have a USB wired mouse. I could try and find this and connect it up and then try and switch Bluetooth off and see if my iMac awakes through night while I'm asleep.

I've found my old wired mouse and have now switched off Bluetooth.

I'll see if my iMac wakes up while I'm a sleep. I'll know if it does as it stays awake and I can hear the hard drive, fan when I go to go on it in the morning.

Thanks for the help. I couldn't make any sense of the Terminal log I posted.
