This is a standard macOS Resource Log (Excessive Writes Report) triggered by cfprefsd, which is Apple's core system service responsible for reading and writing application preferences (.plist files).

The system logged 1.07 GB of written data over 24 hours at a rate of 43.9 KB/s, which crossed Apple's internal diagnostic threshold. No action was taken because this is a background monitoring notification, not a system crash or service suspension.

Adill223, That is not even a question. As a statement it is weird.

You OK?
