System Management Controller
Subsystem of Apple computers
From Wikipedia, the free encyclopedia
Overview
The SMC has roles in controlling thermal and power management, battery charging, fan control, Motion detector, Light sensor, sleep and wake, hibernation, and LED indicators. It also enables enforcement of the macOS End User License, allowing macOS to identify when it is running on non-Apple hardware.[3]
SMC uses ACPI on Intel Macs and RTKIT on Apple silicon based Macs for communication.[4][5]
