macOS Sonoma CSPNEvaluation Wakes USB Drive/Keyboard/Mouse Hourly

Summary: This guide lets you know what macOS Sonoma CSPNEvaluation is and how you can disable it to make your device run as normally. -- iBoysoft

macOS Sonoma CSPNEvaluation

After upgrading to macOS Sonoma 14.1.1, I realized that a wake request named CSPNEvaluation is scheduled immediately after sleep is initiated by the user! This causes the machine to wake up after a specified time (typically 7200 secs, i.e. 2 hours). Does anybody know what CSPNEvaluation does? Is there a way to avoid this request? The CSPNEvaluation request goes like this:

pmset -g log | grep "Wake Request"

Have you encountered this CSPNEvaluation process on your macOS Sonoma, too? If you did, you have come to the right place. The CSPNEvaluation appears when macOS Sonoma users start the Mac computer into Sleep mode, which wakes the built-in fans with a spinning sound and other connected peripherals like USB drives or keyboard with a slight cracking noise made by speakers.

Having investigated this further, however, we found some other users reported that this CSPNEvaluation comes out even though PowerNap is disabled via System Settings or the psmet command is run in Terminal.

Don't worry, yet. This article lets you know what CSPNEvaluation is and how to disable it with a step-wise guide.

macOS Sonoma CSPNEvaluation basic

CSPNEvaluation stands for CoreSmartPowerNap Service which is managed by the power kernel process. It moves the Mac computer installed with macOS Sonoma to wake up when the user starts it into Sleep mode or Power Nap mode, along with the wakened components including connected drives, mouse, keyboard, external display, sound, etc.

After deeper investigation, we found that this came out on macOS 14 Sonoma for the first time and it never occurred on any earlier macOS version like macOS Ventura, macOS Monterey, or more.

It has been verified that this repeated macOS Sonoma CSPNEvaluation happens due to a macOS FeatureFlag for enabling CoreSmartPowerNap in power.plist in the system folder /System/Library/FeatureFlags/Domain/

We cannot edit this plist file directly since it is located in the secure system enclave; however, we can override macOS FeatureFlags by changing them in the /Library/Preferences/FeatureFlags/Domain/ folder. You can follow up to learn how to disable it from your Mac computer by yourself.

  6. Create a folder structure in Mac Terminal by the following command line:sudo mkdir -p /Library/Preferences/FeatureFlags/Domain/
