PS In versions up to 25.11, the CPU load is about 3% when nothing is being done, but in later versions, the CPU load is 30%-40% when nothing is being done.

Are you sure it's only Photshop? What you're done in Photoshop is you see this usage?

Check the CPU usage more detailed.

In Windows there's the Taskmanager to check this. I don't know which the equivalent in MacOS.

Do you have open a image in Photoshop or is it blank?

Try to reset the preferences of Photoshop using the steps described here:

It's recommended to backup your settings before resetting the preferences.

See here:  https://helpx.adobe.com/photoshop/using/preferences.html#backup-photoshop-preferences

Is your system up-to-date? Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver. If you have a NVidia graphic card installed, make sure that you are using the recent Studio version of the driver, not the Game Ready version.

Please provide a copy of your 'System Info'. This can be get from the Photoshop menu item Help > System Info. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.
