![]() ![]() Not high expectations as I have read tons of post on internet and none of them worked by now.Ī runaway kernel_task is a symptom of a problem that needs to be fixed. The computer is clean and BigSur is just installed, so any idea is welcome and I can test anything without risks. Is there any way to fix this? Or BigSur consumes so much CPU in this kind of MBP? and I am forced to go back to Catalina again?. ![]() ![]() It seems the operating system is not the problem (or it is a specific problem with this hardware). I know this is not normal as I have a MacMini 2015 (i7, 3,0Ghz, 16GB) running BigSur without problems using less than a 1% from a fresh boot. WindowServer always on top with 66% of CPU going to 80%, even more sometimes.Īnd Kernel_task always there too with 5% of CPU going to 15%, 30%. Now, the same computer running BigSur, same clean boot, just after a fresh installation from a bootable USB of BigSur 11.3. None app running, just the activity monitor. Here a screenshot of the same computer running Catalina from a clean boot: Mi MacBookPro13,1 (2016, i7 2,4Ghz, 16GB ram) runs slow and it get completely unusable when I need to do normal task (mainly with Microsoft suite: PowerPoint, Teams, OneDrive and Outlook). To give it the latest opportunity I request for help to this forum to try anything to get BigSur running normal. I expected the latest BigSur 11.3 will solve the high CPU consumption, but it is not. I downgraded three times from BigSur to Catalina and it seems that I am going to do it again. WindowServer and Kernel_task always on top. ![]()
