Yeah me again lol

macOS High Sierra and Mojave (and Catalina) will automatically convert all the SSD disks to APFS and macOS Mojave and newer will convert HDDs to APFS by default so you need to patch the installer manually with 3rd party apps.

Hi,

 

Best approach for me was to just boot into USB and run terminal command from USB...

 

WARNING:  modifying the minstallconfig.xml in Target>macOS install data corrupted my installation. I highly do not recommend that approach! 

 

Here is CMD for high sierra   --

 

Only change  the_target_volume to whatever partition trying to install to...

 

/Volumes/"Image Volume/Install macOS High Sierra.app"/Contents/Resources/startosinstall --volume the_target_volume --converttoapfs NO --agreetolicense
