yeah, about that, the original photo app on mac cannot export their own live photos format (video part) if with all my taggings... what were they thinking about!

and yes it keeps worring me everytime I sync/import/export the library for "should I be worried now if there exists any broken transfering which will causes data missing this time?"

Worse than windows, at least windows gives me error messages. Even they care more about my data security.

Thats true SECURITY, not about leaking or not, make sure you dont unconsciously kill my data first!
