| Disable | Enable |
|---|---|
| - Fast Boot - Secure Boot - Serial/COM Port - Parallel Port - VT-d (can be enabled if you set DisableIoMapper to YES) - Compatibility Support Module (CSM) (Must be off in most cases, GPU errors/stalls like gIO are common when this option is enabled) - Thunderbolt (For initial install, as Thunderbolt can cause issues if not setup correctly) - Intel SGX - Intel Platform Trust - CFG Lock (MSR 0xE2 write protection) (This must be off, if you can’t find the option then enable AppleXcpmCfgLock under Kernel -> Quirks. Your hack will not boot with CFG-Lock enabled) | - VT-x - Above 4G Decoding - Hyper-Threading - Execute Disable Bit - EHCI/XHCI Hand-off - OS type: Windows 8.1/10 UEFI Mode (some motherboards may require “Other OS” instead) - DVMT Pre-Allocated(iGPU Memory): 64MB or higher - SATA Mode: AHCI |
