  2. Generate your own SMBIOS: Using OpenCore Configurator or GenSMBIOS, pick a Mac model close to your hardware (e.g., iMac19,1 for Coffee Lake).

Common Boot Errors & Fixes:

  • "Waiting for root device" (Still waiting for root device): This is a USB port issue. Try plugging the USB into a different port (USB 2.0 port, not 3.0). Alternatively, add USBinjectAll.kext and enable XhciPortLimit in your config.

  • Prohibited Sign (🚫): Usually means the firmware is too new (e.g., BIOS 3000+ on certain laptops) or a missing SSDT for your system.
