How to fix powerd 100% CPU usage – macOS Ventura

Fix powerd 100% CPU usage este o anomalie intalnita in aceasta perioada pe sistemele de operare macOS Ventura. Consumul excesiv de resurse CPU al procesului powerd face MacBook / Mac neobisnuit de zgomotos. Este si de inteles. Consumul excesiv de CPU duce la incalzirea procesorului iar sistemul de ventilatie incearca sa-l raceasca. Din fericire exista si o solutie pentru a rezolva acest consum excesiv de CPU al procesului powerd.

De ce consuma powerd 100% – 105% CPU

Problema vine in urma unei caracteristici adaugata de Apple pentru aplicatia Mail pe macOS Ventura, iOS 16 si iPadOS 16. Noua caracteristica a aplicatiei Mail permite utilizatorilor sa programeze ora si data la care un mesaj email sa fie expediat automat. Aceasta operatiune este posibila prin intermediul unui task programat.

 [2]  wake at 04/12/62 02:47:16 by 'com.apple.alarm.user-visible-com.apple.email.SendLaterDelivery' User visible: true

Sistemul de alimentare va incerca sa previna intrarea in sleep pentru a executa task-ul programat, insa lucrurile o iau putin razna si se intra intr-o bucla fara sfarsit in care procesul powerd este utilizat anormal de mult. In mod normal powerd ar trebui sa consume 0.1% CPU, insa se ajunge la 104% – 105% CPU.

Cu siguranta necesita un fix powerd 100% CPU, pentru ca efectiv nu se mai poate lucra pe un MacBook, iar incalzirea excesiva stim ca duce si la degradarea baterieri. t85o381l4ur3n71u

How to fix powerd 100% CPU – macOS Ventura

Solutia cea mai simpla este sa oprim toate task-urile de alimentare programate. Executam in Terminal linia de comanda:

sudo pmset schedule cancelall

Dupa executarea comenzii, powerd o sa scada instantaneu la 0.1% CPU iar ventiloatoarele Mac nu vor mai face zgomot.

Cel mai probabil Apple va rezolva aceasta problema intr-un update viitor al macOS Ventura Beta.

Ca sa nu aveti nevoie de tutoariale precum “How to fix powerd 100% CPU” nu recomand instalarea de versiuni beta decat pe device-uri care nu sunt destinate productivitatii.

In cazul meu aceasta problema a procesului powerd a aparut dupa ce am folosit caracteristica Send Later pe iOS 16. Sincronizarea dintre device-uri a preluat task-ul pe MacBook.
