Ventura 13 Power Events

Recent Upgrade to Ventura 13. Noticed in About this Mac, More Info, System Report, Power, there are Power Events showing suggesting Wake ups at certain times shown below. These did not occur in Monterey. Any thoughts?


Power Events:

In the meantime I found a solution to get rid of the power events. By "I found" I mean actually I found this thread:

Reminders app waking mac from sleep - Apple Community

So I tried it!

Behaviour before the fix:

  • "pmset -g sched" reports our beloved friends

[0] wake at 12/17/2022 00:41:44 by 'com.apple.alarm.user-visible-

com.apple.CalendarNotification.EKTravelEngine.periodicRefreshTimer'.

  [1] wake at 12/17/2022 19:23:54 by 'com.apple.alarm.user-visible-com.apple.acm

  • "sudo pmset schedule cancelall"
  • "pmset -g sched" -> all good!
  • put Mac to sleep
  • wake it up by keystroke
  • "pmset -g sched" -> bad again


Now the fix:

"sudo pmset sched cancelall"

AND

"sudo chflags schg /Library/Preferences/SystemConfiguration/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"


Behaviour AFTER the fix:

  • "pmset -g sched" -> all good!
  • put Mac to sleep
  • wakeup Mac by keystroke
  • "pmset -g sched" -> all good and hope it remains as it is...


Will see tomorrow what "pmset -g log" reports...


Good luck to all...

Hi,


I was upgrading to Ventura 13.1 just 2 days ago and suffered exactly the same problem.

Scheduled power events:

 [0] wake at 12/16/2022 16:03:37 by 'com.apple.alarm.user-visible-com.apple.CalendarNotification.EKTravelEngine.periodicRefreshTimer'

 [1] wake at 12/17/2022 08:00:50 by 'com.apple.alarm.user-visible-com.apple.acmd.alarm'


I was not able to get rid of these power events even by removing the calender widgets and switch off the calender notifications.

Since our future is heading to everything wireless, the environment you're describing sounds really nostalgic :)


Well as for me, I only have one acmd Power Event right now. They get added and removed without any notice haha.


Like they always say, try Safe Mode. Maybe it will remove certain things for you. For a moment when I did that I felt it did it and no more Power Events, but they came back.


Last thing is to chat with Apple to see if they can help you. But I gave up caring. I do wish it just do nothing and just sleep. Like what the Battery sections suggests under Wake for network access, I put NEVER, which I believe should NOT wake it for anything but still do.

Exact same issue.


pmset -g log | grep "Wake Requests"


is littered with:


2022-11-15 03:10:50 -0800 Wake Requests       [*process=powerd request=UserWake deltaSecs=15112 wakeAt=2022-11-15 10:22:43 info="com.apple.alarm.user-visible-com.apple.CalendarNotification.EKTravelEngine.periodicRefreshTimer,593"]           


2022-11-15 03:11:06 -0800 Wake Requests       [*process=powerd request=UserWake deltaSecs=15096 wakeAt=2022-11-15 10:22:43 info="com.apple.alarm.user-visible-com.apple.CalendarNotification.EKTravelEngine.periodicRefreshTimer,593"]

Yes, seen this being discussed in other places. I don't think it's this draining but I could be wrong.


Right now, our main suspects are:

com.apple.alarm.user-visible-com.apple.CalendarNotification.EKTravelEngine.periodicRefreshTimer

and

com.apple.alarm.user-visible-com.apple.acmd.alarm


Can someone please explain what they are doing in the Power Events?


I see CalendarNotifications/RefreshTimer, and I thought it was because some accounts were doing Refresh Calendars: Push, but for Gmail it was timed so I made it Manually to try it out but nothing change. Nothing change as in still wakes from sleep and draining.


The second, no clue.

Nov 16, 2022 2:01 PM in response to Barney-15E

Interesting, and understood.


Well, for Calendar, I don't use it. There might be some holiday events, birthday dates scheduled but that's all.


And those commands do work, but as stated previously, some time later it appears again in the Power Events.


"..gets hung up and drains the battery.."

I only speak for my self here, but first thing from wake:

pmset -g log | grep -e " Sleep " -e " Wake " | tail -n 50

I see the words like Bluetooth and SDXC thrown a few times. For me, I have a thumb drive, monitor (sleep mode), and an SD card 24/7 connected. And like most, bluetooth on with keyboard/mouse. Should I eject everything and turn off bluetooth or something? Maybe I'll try that.

Nov 16, 2022 4:02 PM in response to Barney-15E

Well, (again, I speak for my self) I never even touched the Calendar app. It might synced some Holiday/Birthdays and I see it time to time in the Notification Center, but that's all.


I got this M1 MBP 14 in April, and I remember for a long time it was working fine. I still remember I had it on for 15 days once! But then all of a sudden I started seeing the drain on a random weekend I remembered.

Nov 17, 2022 4:53 AM in response to Barney-15E

I actually did before finding this thread. One told me to do the Safe Mode, and another said to visit a genius bar which I will when I have the time.


But my point of coming back here is like the others, I think we didn't change anything. Since Ventura, or maybe late Monterey, I (we) was experiencing battery drain, and so was hoping someone knows something.

Nov 17, 2022 1:48 PM in response to DeanBGD

Great looking out you guys! I did a report as well. Lets hope this will get noticed.


There should be an option where you allow maintenance tasks/update apps to run when sleep mode on/off, and on battery/plugged in only/always/never. And to who ever is reading this, I know there are some of those options, but yes, when Ventura was released, I spend a good amount of time looking through all the settings. I don't mind when I turn on the computer and the CPU runs wild for a little. Just hate the fact when I sleep the computer wakes up 20+ times every hour for few seconds!

Nov 24, 2022 5:59 AM in response to Daniel Wieder

There are so many power settings or optimize this and that, I'm sure one of them is overriding each other to not work.


Before finding this thread I contacted support about this and they didn't know what those Power Events are either. I mean you work for Apple so it should be easier to find out, right? They just referred me to book an appointment to the Genius Bar which I don't have the time to do right now. Maybe I will try them again.. hopefully lucky and strike a convo with someone that will know. Because I tried three times and I remember the second time the guy was not nice at all.
