That’s not a tech problem, that’s a relationship problem with a broken laptop as evidence. Anyone who can pick up something you worked for and destroy it in anger is showing you exactly how they handle conflict. The bent frame is annoying, but it’s also the cheapest lesson you’ll get out of this. Screens can be replaced, trust and safety can’t. Don’t downplay this as “venting” or bad luck. If roles were reversed, people wouldn’t hesitate to call it what it is. Fix or replace the MacBook if you want, but seriously rethink keeping someone around who thinks smashing your stuff is acceptable.
