Pages Consumes more than 60% on average of CPU capacity!

The tccd daemon (Transparency, Consent, Control) manages the operating system privacy database. Its reported usage will be continuously variable depending on your activity. In Sequoia, I would start in System Settings > Privacy & Security and begin by looking to see if Pages is enabled in the following:

• Files & Folders
  • Pages -> iCloud Drive On
• Full Disk Access
  • I do not have Pages enabled here but that is your option
• Photos
  • Pages - Full access
• Automation
  • Only if you are using AppleScript or Automator with Pages
• Sensitive Content Warning - Off
• Analytics & Improvements
  • All Off
• Apple Advertising
  • Personalized Ads are off
• Apple Intelligence Report - Off
• FileVault - Off
• Lockdown Mode - Off

These reflect my settings on Sequoia v15.3.1. Once you have gone through that list and made any changes, reboot your Mac.

I am watching two tccd processes in Activity Monitor. They are 0.0% and after I open a 180-page Pages document, that changes to 0.2 and 0.4 % respectively for less than 15 seconds, and then they drop back to 0.0%. Pages is using 0.8% of the CPU in Activity Monitor.

I suspect the issue you have has nothing to do with Pages but rather something else you have running on your Mac concurrent with your opening that Pages document.

Do you have any brand of anti-virus or anti-malware application running on your Mac?

I certainly was not recommending the installation of anti-virus software…🙃

With only Pages v14.3 running here and no other applications launched, my tccd percentages are zero. So, I cannot recreate or identify the reason why your tccd values spike in Activity Monitor. It will probably bother you as long as you watch for it in Activity Monitor, and frankly, I rarely launch Activity Monitor here.
