Comment (by kencu):

 looks ike it is optionally used if available. <https://github.com/git-lfs
 /git-lfs/pull/3745/files?>.

 So the Mac way would be to build it against a newer sdk. Alternatively you
 could patch it to disable the function if the header doesn't exist.

 Adding the function to legacysupport doesn't seem possible as it is an
 apsf-specific feature, but it's conceivable a non-destructive similar
 replacement might be found, like using copyfile instead perhaps.
