VirtualSMC

Advanced Apple SMC emulator in the kernel. Requires Lilu for full functioning.

Supports macOS 10.8 and newer (10.9 and newer is recommended)
Implements MMIO protocol and interrupt-based responses for compatibility with modern OS
Properly reports key attributes and r/w protection in the keys
Allows tuning on per-model basis and allows to use different SMC generations
Extensible by the plugins for sensor and key addition support
Enables smcdebug=XX boot argument support on 10.9
Replaces hardware SMC it finds (to disable SMC entirely you need to flash a dedicated firmware)

Add -vsmcdbg to enable debug printing (available in DEBUG binaries).
Add -vsmcoff to switch off all the Lilu enhancements.
Add -vsmcbeta to enable Lilu enhancements on unsupported os (10.13 and below are enabled by default).
Add -vsmcrpt to report about missing SMC keys to the system log.
Add -vsmccomp to prefer existing hardware SMC implementation if found.
Add vsmcgen=X to force exposing X-gen SMC device (1 and 2 are supported).
Add vsmchbkp=X to set HBKP dumping mode (0 - off, 1 - normal, 2 - without encryption).
Add vsmcslvl=X to set value serialisation level (0 - off, 1 - normal, 2 - with sensitive data (default)).
Add smcdebug=0xff to enable AppleSMC debug information printing.
Add watchdog=0 to disable WatchDog timer (if you get accidental reboots).
