Seems this may be SDK version related, so I tried to figure out what the minimum macOS version requirements where for certain applications.

The newer way (binfilename = the filename of your executable):

otool -l binfilename | grep minos

For older macOS versions (I presume before Big Sur):

otool -l binfilename | grep -A 3 LC_VERSION_MIN_MACOSX
