Reminders app waking mac from sleep

I've been having 2 issues with my mac staying asleep, this post is about one of them, which is regarding reminders waking from sleep, turning the display on, and not going back to sleep:


iMac (Retina 5K, 27-inch, 2017). Mac OS 10.15. Have two external USB hard drives hooked up at all times.


In Energy Saver, power nap is off, wake for network access is off. In Notifications, Do Not Disturb has the following 3 checked: "When the display is sleeping, when the screen is locked, when mirroring to TVs".


I set up a test reminder, see the `inDelta=137` below.


Abridged log using `pmset -g log` (full log in attached file):

I have the very same problem as so many others here.


What did work for me, setting an immutable flag to `/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist`:


$ sudo pmset sched cancelall
$ sudo chflags schg /Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist

$ /bin/ls -lO com.apple.AutoWake.plist


This prevents the system from updating the file and my MacBook no longer wakes to reminder events. Needles to mention that it prevents all scheduled system events like sleep, power-on and such.


I recommend removing the flag before a system update:


$ sudo chflags noschg /Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist


Hope this helps at least some of you!

Does 'Safe Mode' allow things like Reminders and Notifications to run? I was under the impression that all those background processes were disabled to provide a really clean and 'safe' operating environment. In which case it would be expected that the problem would not manifest itself in Safe Mode. If the problem does still exist however, then it indicates the underlying sub-systems do run in Safe Mode and the problem is with Reminders and those associated sub-systems.


Not wanting to dismiss your suggestion as any further checking is worthwhile (at least to be able to confirm that with Apple), but I am not sure it would actually tell us anything useful. Is there something else you had in mind?

I am on 10.15.6 - and my computer is woken up by Reminders.


Or does the problem still exist for others even after the (iOS13) Reminders update?

Yes, it does. My situation: I upgraded to iOS13 immediately, upgraded reminders (bad move), and then didn't use reminders on my Mojave machine until one month ago, when I upgraded to Catalina. Since then I have experienced this issue.
