Thinkcentre M93z 0xE issues.

Anyone out there with a Lenovo Thinkcentre M93z with a running hackintosh on the 2020 bios? I was able to successfully install it on the older 2015 bios but not on the 2020 bios as I'm getting 0xE before install. (No idea why, MAT support didn't change and there's no Mmio changes either)

I'm following the dortania opencore guide.

I've tried:

  • Using the same config as the 2015 bios computer.
  • Using the Mac App Store version of Big Sur.
  • Using the macrecovery version of Big Sur.
  • Toggling DevirtualiseMmio.
  • Toggling SetupVirtualMap.
  • Toggling EnableWriteUnprotector (and related options).
  • Switching around between AppleXcpmCfgLock and AppleCpuPmCfgLock.
  • Toggling ProvideConsoleGop.
  • Toggling IgnoreInvalidFlexRatio.


  • CPU: i5 4570S.
  • GPU: Intel HD 4600.
  • Chipset: Q87.
  • Wireless NIC: Intel N 2230.
