Resolved Sleep Issues Mac Mini

[Ezswo]

A couple of days ago I discovered that my Mac Mini keeps waking itself up about 450 times a nigt! The moment it goes to sleep it wakes itself up again. I suspect this is happening from the time I installed MacOS Sierra a couple of weeks ago.

I searched the net for this problem, but never found a Mac which wakes up so many times. With the command "pmset -g log" I can see the logging from those wake up cycles. Below I will post a portion of it and these lines just keep repeating themselves over and over again. I don't know where to start so I hope that some of you can interpret these lines for me, so I know where to start looking.

I realize this is not a "direct solution" to the wakeup problems you're experiencing, but what follows is what I do:

- connect Mini (and all close-by AC powered peripherals) to a surge protector with an on/off switch
- at night, shut Mini down, then reach down and TURN OFF the surge protector
- in the morning, TURN ON the surge protector and then press the Mini's power-on button.

No worries about unscheduled or unplanned activities at night... ever!
(been doing this with my Macs for 25+ years...)

Hi Fishrrman,

Thanks for your reply. I thought about your option as well, but it would mean that my MacMini will still be waking up every day for about 200 times... The problem is (or was?) that it would just wake up hundreds of times a night AND day.

After doing about everything I could find on the Internet on wake/sleep problems I tried the Obvious yesterday. Shut the Mini down, pulled the powerplug for about 20 seconds, put it back in and turned the Mini on again... and behold, it's sleeping again without interruptions.

So, I feel pretty stupid right now for not trying this earlier... So, for now it seems okay...

Your Mac talks to Apple during sleep and sometime the power cycle accidentally wakes it and creates a habit. It very common with laptops...first I am hearing of the issue with Mini...of course, my Mini never sleeps. Be sure you uncheck wake for Ethernet network access in System Preference > Energy Saver.

Your Mac talks to Apple during sleep and sometime the power cycle accidentally wakes it and creates a habit. It very common with laptops...first I am hearing of the issue with Mini...of course, my Mini never sleeps. Be sure you uncheck wake for Ethernet network access in System Preference > Energy Saver.

Thanks for your reply. Although my problem is already solved with resetting the SMC form my MacMini, I would like to reply to this. I found this "solution" about the ethernet network acces on several forums. But, this function has a useful purpose, so unchecking this is no solution at all. It's just unchecking an option which limits the use of my MacMini. I use, for instance, the Plex remote app on my iPhone which can wake my Mini. This will no longer function. I cannot wake my Mini from my iMac for maintenance (I have no keyboard or mouse on my Mini).

So, I never understood this solution. Wake and sleep should also be working correctly with this function checked. I "just" requires more information/investigation on what exactly is waking the Mac when it's checked. I uncheck this option only for investigation purposes to see if it helps (which didn't in my case). I wouldn't recommend unchecking it when you want acces to your Mac from other devices.

No problem...just sharing what works on my laptop. Hope you know every couple of days you'll need to reset SMC...I have to do this with my laptop even with the uncheck option.
