cow.diff: I'm not sure that attempt to call unlink() if FICLONE fails is a good idea. unlink() can raise a new exception which can be confusing. IMHO it's up to the caller to deal with that. Said differently, I dislike the *fallback* parameter of reflink().

Why not exposing clonefile() as os.clonefile() but os._clonefile()?

+#if defined(MAC_OS_X_VERSION_10_12)
+#include <sys/clonefile.h>

Is Python compiled to target macOS 10.12 and newer? Mac/BuildScript/ contains:

DEPTARGET = '10.5'

But I don't know well macOS. "#if defined(MAC_OS_X_VERSION_10_12)" is a check at build time. Does it depend on DEPTARGET? Would it be possible to use a runtime check?

You might open a dedicated issue to expose clonefile() since it seems like every tiny detail of this issue is very subtle and should be properly discussed ;-) (I like the idea of exposing native functions like clonefile() directly in the os module!)
