在原有Clover引导基础上迁移至OC，已对配置进行优化，当前使用环境与项目所示配置除网卡使用1820A外其余一致，目前使用正常，已解决开机USB卡顿问题，CPU正常变频，目前存在问题与之前差不多：1、无法实现4K60Hz（已调显存无果）2、风扇转速无法读取（之前clover也无法通过Macs Fan Control，不知原因，已就该问题修复SMBus但无果）。另外，本环境已关闭CFG Lock锁，BIOS版本A16，CFG目标开关为0xD9F（0x00为关），若无关闭CFG将无法进入系统，需修改config中Kernel-Quirks-AppleCpuPmCfgLock和AppleXcpmCfgLock为True。目前问题如上，如有其它问题请及时交流

https://github.com/ismethr/9020mHack 可以尝试一下，目前使用2K，120Hz没问题，没有4k不能测试。USB需要定制一下，其他的没啥了 |

我看配置framebuffer-stolenmem给的是DVMT 128m的，记得提醒下，DVMT也要跟着改动。 64m 对应00000004 DVMT 0x263 0x2 我测试96m 也可以正常驱动4k。 |

兄弟更新得有点多，考虑要不要单独拉个分支 oc 和 clover 并存一段时间 |

Hello mingcheng ;) I would be very thankful!你好明成;） 我将非常感谢！ |

我用了 zearp 的最新 OC 配置， 目前一切正常 |
