Hi all, I have recently installed the public beta version of Ventura on my 3.1 GHz Quad-Core Intel Core i7 MacBook Pro. My fans were constantly running because of an activity in Activity Monitor “powerd” showing 104% CPU usage.
I tried everything but found it to involve schedules set behind the scenes that wake/sleep the laptop. Without going into too much detail, the following when executed in Terminal will kill/reset the process and actually work. Rebooting, killing the process, and trying other Settings and Terminal solutions failed to yield results.
sudo pmset schedule cancelall
This worked like a charm.

Add a CommentAgree. Found the same solution and explanation here: https://www.reddit.com/r/MacOSBeta/comments/wb0sh4/fan_wont_stop_spinning_on_idle_after_i_updated_to/
The same thing also happens on M1 and M2 Macs, but you would not notice, because the device is not getting hot and the fans are not spinning loudly. I just wanted to mention it, because there are rumors on the web that it only affects Intel based Macs.
