Save your M-series Mac’s energy and battery
How your Mac can use less energy and power, run its battery down less, generate less heat, and keep its P cores for the work you want it to do for you.
For the last nine years, Apple silicon chips in iPhones and iPads, and most recently Macs since 2020, have had Efficiency cores, designed to eke out their use of power to extend battery time and stay cool. In-app controls Although the code run by apps can’t be directly allocated to P or E cores, macOS can get a strong hint by a setting known as the Quality of Service (QoS). Cormorant, a much simpler compression utility aimed at AirDrop transfers, has a fourth slider position with a pointing hand 👉 that allows you to set a custom number of threads and QoS level, as I also use that to test and compare P and E cores.
