苹果系统之家

VirtualSMC是高级的 Apple SMC 核心模拟驱动，让苹果系统以为当前启动的电脑是Mac电脑，需要 Lilu 作为依赖以正常工作。

特点

• 支持 64 位的 macOS 10.6 以及更新系统 (推荐使用 10.9 及以后的系统)
• 实现 MMIO 协议以及适配现代版本 macOS 的中断响应机制
• 正确提交键值属性以及它们的读写保护
• 允许根据机器型号动态调节使用不同代的 SMC
• 支持通过插件添加可扩展的传感器
• 支持启动参数 smcdebug=XX (10.9+)
• 替换查找到的硬件 SMC (你需要刷写特定的固件来完全禁用 SMC)

启动代码

• 添加 -vsmcdbg 以开启 debug 输出 (需要 DEBUG 版本支持)。
• 添加 -vsmcoff 以禁用所有 Lilu 增强。
• 添加 -vsmcbeta 以在不支持的系统中启用 Lilu 增强 (11 及以下版本为默认开启)。
• 添加 -vsmcrpt 以报告缺失的的 SMC 密钥到系统日志中。
• 添加 -vsmccomp 以优先使用硬件 SMC（如果有）
• 添加 vsmcgen=X 以强制暴露 X-gen SMC 设备 (支持 1 和 2 代)。
• 添加 vsmchbkp=X 以设置 HBKP dumping mode (0 – 关闭, 1 – 普通, 2 – 没有加密)。
• 添加 vsmcslvl=X 以设置 serialisation level 的值 (0 – 关闭, 1 – 普通, 2 – 包含敏感数据 (默认))。
• 添加 smcdebug=0xff 以启用 AppleSMC debug 信息输出。
• 添加 watchdog=0 以禁用看门狗 (WatchDog) 倒计时 (if you get accidental reboots).

传感器 Kext 作用

• SMCBatteryManager 添加 SMC 跟 SMBus 协议完整的 AppleSmartBattery 模拟层，电池相关的传感器
• SMCLightSensor 通过新的 SMC 事件 API，是一个光线传感器的例子 (需要 ACPI0008_ALI)

v1.2.0

• Improve manual fan control in SMCDellSensors (switch off manual control before going to sleep), rename control boot-args (start with -dell)

v1.1.9

• Improve manual fan control in SMCDellSensors (use control registers 0x35a3 and 0x34a3 to cover more Dell models)
• Fix processKext in SMCDellSensors (could be called multiple times for the same kext since flag Reloadable was set)
• Reduce audio lags in SMCDellSensors when USB audio device is used
• Allow not injecting TB0T SMC key when it is unavailable in SMCBatteryManager

v1.1.8

• Reduce audio lags in SMCDellSensors

v1.1.7

• Added MacKernelSDK with Xcode 12 compatibility
• Fixed SMCDellSensors loading on macOS 10.8

• Fixed rare kernel panic in SMCSuperIO

1.1.6

• Added battery supplement info, thx @zhen-zen
• Fix audio lags in Safari caused by reading SMM in SMCDellSensors plugin
• Fix module version for SMCDellSensors, SMCBatteryManager and SMCLightSensor
• Optimised floating point sensor key reading with fewer arithmetic operations
• Improved SMCProcessor CPU power consumption by relaxing core synchronisation
• Fix key sensor key enumeration on Macmini8,x and MacBookPro models

v1.1.5

• Improved CHLC key value reporting
• Fixed B0PS and B0St key size to resolve broken fully charged state
• Fixed sometimes stuck battery update thx to @zhen-zen
• Added workaround for kBRemainingCapacityCmd exceeding kBFullChargeCapacityCmd
• Added preliminary 11.0 support
• Fixed SMCProcessor model detection warning
• Fixed legacy smc tool value calculation
• Fixed running smcread on 11.0 without IOKit framework
• Added a new plugin SMCDellSensors for Temp/FAN monitor/control
• Added basic SMCBatteryManager compatibility with 11.0
• Fixed crashes when trying to read CLKT key

v1.1.4

• Fixed incorrect revision reporting on T2 models (e.g. Macmini8,1)

v1.1.3

• Fixed compatibility with 10.15 debug kernel with traptrace enabled

v1.1.2
