IMDPersistenceAgent hogging CPU since Sonoma

Since updating to Sonoma there has been this IMDPersistenceAgent hog taking 30-50% of the CPU power! I have seen older complaints here suggesting a reset of the NVRAM which I have done several times to no avail. Force quitting does nothing but essentially restart it. This is absurd for such non-essential process.


How can I stop this undue theft of CPU power??

MacBook Pro 13″, macOS 10.15
