If the process' powerd’ uses high resources of CPU pe Mac, you are not the only one who gave this problem. It seems, the problem is very present on all models of MacBook with operating system macOS Ventura.

The consequence of high use of a CPU (visible in Activity Monitor), by any process, it is the overheating of the device and the noise produced by the cooling system, which is difficult to maintain the optimum operating temperature for the processor.
In this tutorial you will learn how to solve the problem in which the process' powerd’ uses high resources of CPU pe MacBook, but also what this process is.
What is the process' powerd’ And what helps?
As the name suggests, 'Powerd’ It's a “daemon” of the maccos operating system, which deals with the management of energy resources on the MacBook. The process regulates the energy settings of CPU, including frequency and number of active nuclei to maintain a balance between energy performance and efficiency.
‘powerd’ It is very important in optimizing the battery life and maintaining an energy consumption as efficiently as possible, especially in the case of use on portable devices such as MacBook or MacBook Pro, as I said above.
The process' Powerd’ Does it use large CPU resources on Mac? What you have to do in this situation.
The first problems in which the process' Powerd’ they appeared on macOS Ventura, when Apple introduced the scheduled shipping feature of email messages. While waiting for the action in Task, the process ‘powerd‘ pushed use CPU and over 100% of capacity.
If you are experiencing an excessive use of the processor, it is good to check the list of scheduled actions. open Terminal and execute the order:
% pmset -g sched
Scheduled power events:
[0] wake at 04/12/62 02:47:16 by 'com.apple.alarm.user-visible-com.apple.email.SendLaterDelivery' User visible: true

To solve this problem, the simplest is to stop all scheduled tasks, concerning energy management on MacBook. Including automatic input tasks in module “sleep“.
open Terminal and execute the command line:
sudo pmset schedule cancelall
After executing the command line, “pmset“, all the scheduled actions will be canceled, and the consumption of resources of the process ‘powerd‘ will return to normal.
It is important to note that the cancellation of all events can affect how the energy consumption of MacBook.
