Big Sur powerd process constant CPU 100%

I have the same thing here on my Macbook but I'm still on Catalina (10.15.7). It's driving me nuts! Can't track down anything that looks relevant at the moment, either.

Code Block 
Process powerd.177 Created UserIsActive "com.apple.powermanagement.wakeschedule" age:00:00:00  id:38654742746 [System: PrevIdle DeclUser kDisp]

Any solutions to this? I'm on the 11.0.1 public release and this is an issue. My computer is beach balling and my fans are running at the same during the simplest of tasks.

Same here, after upgrading to Bug Sur the CPU has been at 100% and my battery is emptying every couple of hours from full charge! Lately the umount root process is been at 100%, multiple restarts are not doing the job. Apple, please respond!

I had the same issue on both my 2019 iMac 27" retina and my 2019 16" MBP. I spent several hours with apple support on the phone over 3 different days. I sent diagnostic reports and such. They didn't want to help as Big Sur was in beta still. They wanted me to downgrade before diagnosing.

I told them I would wait until the release of Big Sur and see if it went away, which it did not. Then I said I would get back with them if there was still an issue as it should then be supported. There were still no fixes from Apple.

The only fix I was able to find was to set a schedule in the power saving preferences. I set the schedule to wake everyday at 12:00am and sleep at 12:01am. This corrected the powerd issue immediately, although it created issues on my iMac which had 3 external displays connected to an external GPU. The moment the system would go to sleep for any reason, it would cause a kernel panic in the watchdog process. It was only related to sleep as if I set a screen saver, it did not cause a panic until the computer tried to sleep.

I sent a crash report to apple every morning as my computer never gets shut off and it would crash and reboot sever times every night.

I removed every external device, reset the memory controller and every type of reset apple could think of. Nothing fixed the issue.

I finally wiped my entire system by deleting the entire contents of the SSD using the disk manager in the recovery console and then doing a clean install of Big Sur from there after. After the fresh install, all seems to be normal. I have reinstalled every application and reconnected every device to both my MBP and iMac. Powerd is no longer an issue!!!!

I suspect something in the beta installer process on one of the versions corrupted something in the power management. On my MBP, when I search for powerd, the process does not even exist. I cannot remember if it exists on my iMac and I don't have access to it at the time I am writing this. I believe at one point I searched it and found it. At another point I think it was not found. Possibly, is it a process that was created in a previous version of MacOS and Big Sur doesn't know what to do with it? I doubt that but just throwing it out there.

All has been well on my iMac for two weeks now and my MBP for 2 days now....

I've been having the same issue on my MacBook Pro (15-inch, 2018) since I updated to macOS Big Sur 11.1 beta 2: the "powerd" process uses more than 100% of the CPU (usually about 104%), and neither quitting it manually nor restarting makes a difference. Thankfully, YukonJJR's trick with setting a schedule in the Battery pane in System Preferences seems to have worked. When there's no schedule enabled, the following messages appear multiple times per second in Console:

Process powerd.899 TimedOut InternalPreventSleep "com.apple.powermanagement.wakeschedule" age:00:00:05  id:55834610560 [System: DeclUser kDisp]

Wake timer expired for com.apple.alarm

(I found these messages by filtering the log with a search for "powerd"; it's possible that I missed some other messages that didn't include the string "powerd".)

Once a schedule is enabled, the messages no longer appear. For what it's worth, only a "Start up or wake" schedule works; "Sleep", "Restart", and "Shut down" schedules don't seem to do anything.

I would file a feedback report, but the Feedback Assistant server is down right now. I just submitted a feedback report ("FB8929860").

Same issue, happened with last update (After weeks of trying to work with apple, only solution was to **** my computer).... and now its back. I remember when apple even if crazy expensive had good tech. Are they not getting good enough engineers? Like what is this issue, and how is it going to go on for over a year...

Great example is this post. 3 months. multiple people with same issue. No response from Apple...

is this ever going to be addressed by apple? this has been happening for years. i would have thought that there would at least be a support page for this by now, instead of all these unanswered posts across so many forums (apple, stackoverflow, gitter, github, medium, etc).

Got the same problem 6 month after your post! Just made the upgrade to BIG SUR (11.2.3) yesterday and my fans go crazy, the battery goes empty in 1h on my MacBook Pro 15" from last year. The apple phone call can't help me after trying a few things like restart the mac doing a few things. They ask me to erase my HD and install everything again properly... but I'm not happy with this solution! So I tried to schedule the wake up as described by an other user and it works well! I hope this bug will be deleted in the next upgrade!!!

Same here, since update to Big Sur, my MBP 16 2019 runs on 100% CPU usage, process is configd. Cannot work anymore. Not help found in Internet... So I use my other laptop now, its on Linux.

I'm experiencing the same problem after upgrading to Ventura Beta 4 (I guess it went full circle, huh). Although the schedule thing does fix it (although now I have to do it in Terminal since it's missing for some reason), I honestly don't want to have to do such. I really hope this doesn't happen again when they release the stable release (for that matter, please release it soon).

Hi RWMacs,

"although now I have to do it in Terminal since it's missing for some reason"

could you please post how you do that. No energy management in VENTURA (so far)....

Thank you, let's see what happens now, looking good!!! My Mac took nearly no time to start up, before it took forever...

I created this video because this worked for me practically instantly:

Hope it can help someone.

Cool, "sudo -i" was what I was missing...

"powerd" is behaving nicely as of yesterday, but: There where two new events today, that I did not set. One for x.x.22 and one for x.x.62. Doesn't make sense... But as long as "powerd" is behaving, I guess I can live with it.

Followed your video again and cleaned out the tasks AGAIN, let's see, if they come back again.
