Even the "top" download can hit roadblocks. Here are fixes for common issues:
| Error | Solution |
| :--- | :--- |
| Stuck at "End RandomSeed" | Disable Above 4G Decoding in BIOS or enable DevirtualiseMmio in config.plist. |
| AppleIntelCPUPM panic | Add -no_compat_check and cpus=1 boot-args for first boot, then fix with SSDT. |

| Grey screen after login | Disable NVIDIA injection or boot with -igfxvesa to disable graphics acceleration temporarily. |
This is the #1 failure point. Download Hackintool and map your USB ports to create USBMap.kext. This prevents sleep/wake issues and USB 3.0 dropouts.
