System Management Controller
The System Management Controller (SMC) is a subsystem of Intel processor-based Macintosh computers. It is similar in function to the older SMU or PMU or UAE of non-Intel Macintosh computers.[1][2]
Overview
The SMC has roles in controlling thermal and power management, battery charging, video mode switching, 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]
gollark: You mean, combine their bytecode or something insane?
gollark: That's basically what this does?
gollark: ```lualocal func_mt = {}debug.setmetatable(function() end, func_mt)function func_mt.__sub(lhs, rhs) return function(...) return lhs(rhs(...)) endendfunction func_mt.__add(lhs, rhs) return function(...) return rhs(lhs(...)) endend```
gollark: No clue what `..`, unary `-`, `/`, `*` or `^` should do.
gollark: `+` is right-to-left compose, `-` is left-to-right compose.
