what is powerd and why is it using so much cpu

powerd is owned and started by root i.e. the system and won't listen to a friendly stop. You can do a forced quit, the system will restart the process automatically after killing it, no need for a reboot.

If powerd was running nuts and if the activity monitor was open, it will prob. "replay" or better catch up all the data it has missed for a while. On a Mini server it took about 5min! until the activity monitor catched up and was back to normal after killing the powerd... Apple should really fix this.

It is something related to power management, but it shouldn't be running away like that.

Select it in Activity Monitor and then Quit it using the "X in octagon" button. You should only need Quit, but try force quit if needed.

It will restart, but hopefully it won't start running away. If it does, there is likely something else causing it to do that.

Thanks my Mac Pro (Early 2008) did the same thing after i used "CleanMyMac 2" which was also going crazy even after I Quit it. so I had both the powerd and "CleanMyMac 2" trading places as the top power and Memory users. I finally forced quit "CleanMyMac 2"in Activity monitor. and just quit powerd in activity monitor. thanks again

To recover from the effects of having used CleanMyMac, read below.

It is not reasonable to expect a Mac to operate normally after using CleanMyMac. Like many ill-conceived "cleaning" utilities, it is capable of corrupting a Mac to the point that erasing it completely is the only practicable means of recovery. CleanMyMac is not the only example; it is merely popular due to marketing strategies that are as effective as they are intrusive.

There is no practicable way to reverse the effects of having used CleanMyMac2 other than to reinstall all affected files from backups or their original sources. Its developer's uninstallation instructions are ineffective despite their recent claims to the contrary. Only MacPaw, its developer, can know the reason for that, but I can think of two possibilities: either they are purposefully leaving components behind for reasons known only to them, or they simply don't know what they're doing. Neither one of those possibilities is particularly comforting for the user.

Reinstalling OS X alone will have no effect on either removing CleanMyMac or reversing the damage it is capable of inflicting upon a system.

Follow the applicable recovery procedure below:

• If you have a backup that you created prior to using CleanMyMac, now is the time to use it. For Time Machine, boot OS X Recovery, and at the Mac OS X Utilities screen, choose Restore from Time Machine Backup. Choose a date preceding the installation of CleanMyMac.
• If you do not have a backup that predates the use of CleanMyMac, create one now. To do that read Mac Basics: Time Machine backs up your Mac.
  • The recovery procedure will require that you erase the Mac using OS X Recovery, and then create a new user whose contents will be empty. You will then be able to use Setup Assistant to migrate your essential documents including photos, music, work products and other essential files.
  • When doing so, select only your previous User account and do not select "Applications", "Computer and Network Settings" or "Other files and folders". De-select those choices.
  • Subsequent to using Setup Assistant, you will need to reinstall the essential software you may require, once again remembering to install software only from their original sources, and omitting all non-essential software.
  • "Non-essential software" is a broad category that includes but is not limited to third party "cleaning", "maintenance", and "anti-virus" products.

To erase and install Yosemite read: OS X Yosemite: Erase and reinstall OS X

To migrate your essential documents read: OS X Yosemite: Transfer your info from a computer or storage device and follow the procedure under Transfer info from a Time Machine backup or other storage device.

Thanks John I appreciate your wisdom

I had this problem and after reading your post I used 'Tinker Tool System' to remove 'Clean my mac' and hopefully its components. I then quit powerd in Activity Monitor. So far, so good. powerd is now showing 0% CPU use. Thanks John for pointing out the culprit.

I am having the same problem with powerd.

I have not used "clean my my" or any other product like that.

powerd will use as much as 70% of the CPU.

I have killed it using Activity Monitor only to have it come back again, although not immediately.

It is currently failing on my mac-mini, but I have also had it fail on a MacBook Pro.

This did not happen until after I upgraded both systems to Yosemite about 2 months ago.

Although I thought I'd solved the problem, it did in fact return. I had a search around and found a folder called CleanMyMac, containing the file infodictionary.plist. It was still there even though I uninstalled CMM and also ran the Tinker Tool System on it. Anyway, I deleted it and all seems well again, fingers crossed.

I'm certainly no expert but I would have thought your problem would be something similar, not necessarily related to CMM but a left-over from some previously deleted software.

Start a new question and include an EtreCheck report.

Same here. Every other week or so. I have an uptime of 55 days. And done it 3 times. Everything is unresponsive. Force quit window see's 2 process for each process. Force quit powerd and Activity Monitor freaks out and just runs text over and over. Finally quitting in like 30 secs. Back to normal. Super annoying. Have to wait 10 secs for every click action. Prior to that there were restarts but that is not the issue. Maybe they have to revert to powerd from 10.8. lol. 2008 Mac Pro, 12GB Mem, Radeon 5770.

I think you should reset your SMC

with Imac, mac pro, mac mini:

Shutdown the computer, unplug power chord, wait 1 minute, plug the power chord, start the computer.

with macbook, macbook pro:

shutdown the computer, press shift+ctrl+alt, while you press those 3 keys, press power button, you will see the led of your power chord switching, it should not start. Then, release the 3 keys and start the computer.

I have several Macs (a few Mini servers, and laptop) and they all are showing problems with powerd burning too much CPU. This started with 10.10.x (I think 10.10.4 but I could be wrong) and is still happening with 10.10.5.

On the Mini servers, it's terrible: powerd will hit 100% cpu and sit there for hours or days.

On the rmacbook pro, it's not as bad (Right now I see powerd hanging at about 20%)

Of note, both Minis are plugged into UPS over USB cables and have some sleep settings for the UPS (System Preferences / Energy Saver / UPS).

But the Retina Macbook Pro is not.

Frustrating. Any ideas?
