High CPU Usage from peopled After Updating to macOS Tahoe 26.4

Hello,


I recently updated my MacBook Air (M4) to macOS Tahoe 26.4. Since the update, my system has been experiencing unusually high CPU usage from the process peopled, which consistently stays around 70–80% CPU.


Because of this, the MacBook becomes noticeably warm and the battery drains much faster than normal, even when the system is mostly idle.


I have already tried the following troubleshooting steps:



  • Force quitting the peopled process using Terminal (killall -9 peopled)
  • Restarting the Mac
  • Resetting Spotlight indexing
  • Restarting related services such as contactsd


However, the issue persists and peopled remains the top CPU-consuming process in Activity Monitor.


This problem started immediately after updating to macOS Tahoe 26.4 and has continued for the past two days.


Could you please help diagnose and resolve this issue?

MacBook Air 13″, macOS 26.4

The problem for me was that the peopled process was trying to access a file (console logs show repeated errors accessing $HOME/Library/Application Support/CallHistoryDB) that was quarantined. Removing the quarantine flag and restarting the daemons fixed it.


# Are the CallHistoryDB files quarantined? (shows com.apple.quarantine)
ls -lan@ "$HOME/Library/Application Support/CallHistoryDB"


If so then you can remove the quarantine flag and kill the process to restart them.


Note, the xattr -dr command needs your terminal app to have Full Disk Access (System Settings / Privacy & Security / Full Disk Access). Without it, you'll get permission-denied on the xattr write. Grant it, restart the terminal, retry.


# Strip the quarantine attribute from the CallHistoryDB tree
xattr -dr com.apple.quarantine "$HOME/Library/Application Support/CallHistoryDB" 

# Verify it's gone (should show no com.apple.quarantine lines now)
ls -lan@ "$HOME/Library/Application Support/CallHistoryDB"

# Restart the daemons; launchd will respawn
sudo killall -9 peopled CallHistorySyncHelper

Not an issue here Tahoe 26.4.1 on 3 different M-Class computers


If we may inquire regarding the Contacts application and sync to iCloud which my 3 machines also use.


Contacts do work well with iCloud and not so well when a Second Source is associated with Contacts , like Google or some other Cloud Based syncing source

The use of Console Logs for troubleshooting was last effective during the time of OS X 10.6 Snow Leopard.


Since then, Console Logs have evolved into a language exclusively understood by Software Engineers.


It is recommended to explore alternative methods when attempting to troubleshoot the “peopled” issue.

Exactly the same. Out of nowhere. I tried all the steps to no avail, except for the contacts which I will try tomorrow as I am tired. This is a brand new M4 MacBook Air, 15 inch and now I’m worried that this excessive CPU usage with the heat and the rapid battery drain (about 1% drain every 1 to 2 minutes) is going to create premature wear on my machine. I’ve had this miracle machine for two months, and with 24 GB ram this thing has not gotten even slightly warm to the touch or felt taxed in any way this entire time. The battery literally would last all day with heavy usage. Now it drains 20% within an hour.
