What's the minimum Mac OS that built apps support?

I seem to be getting conflicting information.
One says it uses a version for Mac OS 10.13, and also says minos is Mac OS 11.0.

otool -l /MMF2Lib.framework/Versions/A/MMF2Lib  | grep -A 3 LC_VERSION_MIN_MACOSX
      cmd LC_VERSION_MIN_MACOSX
  cmdsize 16
  version 10.13
      sdk 13.0
otool -l /MMF2Lib.framework/Versions/A/MMF2Lib  | grep minos  
    minos 11.0

10.13 would be High Sierra and later, whereas 11.0 would be Big Sur and later.

10.13 would be High Sierra and later, whereas 11.0 would be Big Sur and later.

My best guess is that the reason for the 2 different version numbers are due to the fact that Mac apps now contain both Intel and M1 code. High Sierra (10.13) is the minimum requirement for Intel machines, while Big Sur (11.0) is the minimum requirement for M1 machines. The reason for the difference likely comes down to the fact that M1 Macs cannot run anything older than Big Sur, but since Intel Macs can, the requirements were lowered for the Intel part of the application.
