Why is coreaudiod and locationd using 150% CPU on Sequoia 15.4?

Hi all


After updating my Macbook Pro 14" M3 Pro to Sequoia 15.4 both coreaudiod & locationd have over 150% CPU in Activity Monitor ? My Macbook Pro I9 Intel does not have this issue.

Anyone else with this ?


Thx

On my 15.4 M1 Studio Max system coreaudiod is 0% and locationd is 3.8% currently. So I doubt it's some kind of bug. Possibly a glitch that occurred during your installation. Try restarting in Safe Mode and test.

New update.

  1. coreaudiod is (in my case) related to Boom3D. It is not enough to quit the app, but you must also delete the two 'global delight…' plist-files, reboot and not letting it start at log-in. I've contacted Globaldelight.
  2. locationd: First it seemed a new user fixed it. But it was again Activity Monitor showed only the users processes.

You might try turning off Location Services, then turning it back on.


System Settings->Privacy and Security->Location Services->toggle off. Restart and toggle back on. Also take a look at which apps are currently using Location Services. Apps using Locations Services will have little dark arrow next to them. Anything out of order there?


One last trick, kill locationd. In Activity Monitor, select locationd, double click and select Quit. The system will reestablish it on its own.

I managed to get rid of this issue, by moving over all the files in ~/Library/Preferences and copying them back in chunks + reboot.


I'm not quite sure which one(s) caused the problem. After putting back all files, the issue was still gone. So it's quite confusing. Maybe some cached plist-files got fixed.


This seems to also have fixed printing being super slow after 15.4 upgrade.

Well, I’ve reached the extent of my expertise in this matter. Perhaps another user with more knowledge of this problem will come along with suggestions.

Hi man and thx for all your suggestions but i already tried all those tricks and still the same.

I even re-installed the OS through Apple Recovery and still the same. Super weird.

When Location service is disabled it still shows 170% CPU in Activity Monitor. So i tried everything i can think of and also your tricks.


Then i tried locating the actual locationd file from inside Activity Monitor and in Finder i double-clicked on the locationd and it opened in Terminal witch is right and showed this.

I can see something error related in the text. Incorrect NSStringEncoding and also authenticateUsingAuthorizationSync error.


No idea what that means.

Its a strange thing ? I wonder why this happens.

It started on my M3 Pro after updating to 15.4 and i could never stop it. had to do a complete re-install :(

But more strange was my old MacBook Pro 2018 i9 Intel suddenly started after 1-2 days of running 15.4 ???

Super weird, why not right away like my Apple Silicon Mac, it came after around a day and then disappeared again after half a day. Mysterious really.
