duetexpertd using 100+% of my CPU, on Mac Mini M4, on Sequoia and on Tahoe.

I have Siri, iCloud, Handoff, and Apple Inteligence turned off, including each and every individual app that would use Siri. Nor do I sync any iCloud information from my Mac M4, nor my Mac M1, to iCloud. iCloud is all turned off. I rarely use my iPhone 8 connected to my Mac, other than to receive music files over wi-fi and then using only a non-Apple application, and I never back the iPHone up to the Mac. Nor have I ever used 'Handoff' with any device on a Mac. I have recently, today, reindexed Spotlight. If no one on this forum provides a legitimate solution to this issue soon, I will disable SIP and then use Terminal to remove the duetexpertd and DuetActivityScheduler related files. 2025-09-18.
