Hello I'm Sagnik Ganguly, I'm trying to dual boot macOS 10.14 and Windows 10 (already installed) on a PC with Legacy BIOS. I've two hard drives one in where the windows is installed and another which is converted to GPT to install macOS Mojave 10.14 with a partion of Mac OS Extended (Journal) or APFS but when I went to the Install Disk Selection page, I'm selecting the partition but it says "This version of macOS 10.14 cannot be installed on this computer." can you help me please? 

P. S. My motherboard doesn't support UEFI. 

I'm attaching some pictures of the screens.

Which SMBIOS are you using? it needs to match the list of supported Mac models...

 

An example: Up to High Sierra, my old C2D Dell Vostro 200ST ran with iMac10,1 SMBIOS. Impossible to install/run Mojave or Catalina with such SMBIOS, iMac10,1 is not a supported platform. I had to switch to a supported model such as iMac13,2 to run those macOS versions.

      A few days ago I faced a problem - installed ocquirks and it somehow broke my prelinked kernel. System won't boot then, and I spent more than a day restoring from the netatalk  backup to copy working prelinked kernel directory from the backup to the s/l
      So, my question is - how to relink prelinked kernel without that? I found boot args -f UseKernelCache=No but it didn't work. I was able to boot to the recovery, if that can help.

      Hi, I'm receiving these two errors before the system automatically reboots.
      36:296 00:063 OCSMC: SmcReadValue Key 4D535463 Size 1 36:351 00:054 OCSMC: SmcReadValue Key 4D534163 Size 2  
      Using OpenCore 0.5.7, Mojave 10.14.6 installed successfully (from USB, but have not gone through OS setup ie. 'select your country' screen yet) but now selecting the Mojave drive in the boot picker results in the above error.
      Hardware is Gigabyte H77-DS3H, Core i7 3770 (Ivy Bridge), Radeon Sapphire RX 580 Pulse, 16GB DDR3 ram.
       
      I had a fully working 10.14.4 install running OC 0.5.6 prior to this.

      OpenCore log and config.plist (with SMBIOS serials etc removed) attached - any help greatly appreciated.
       
      Thank you.
