Thank you for your suggestion, but I do not succeed with it. I fail to take a CPU offline on my M1 mac: "cpuctl: processor_exit(i) failed" Moreover, I can't discern the core type from the cpuctl list since all cpus are of the same "type". I assume it is easier to activate the "power safe mode" then. Of course, the disadvantage of these approaches is that the whole system gets slower.
