It's intellectually unsatisfying to think that superdeterminism could relate to something as supremely complicated as a scientific apparatus:
Why do you say that? If the whole universe is deterministic, then of course every part is deterministic. A scientific apparatus is incredibly simple compared to the universe as a whole.
Perhaps what you mean is that you want to know what mechanism creates the appearance of randomness/entanglement/free-will in a fully deterministic universe? Why does it appear that your actions have an influence on distant events, and that influence takes the form of a certain type of correlations between observables? It would be unsatisfying to declare, "It just happens, and there's no reason for it. It was just predestined that you would make the choice consistent with those correlations - for no reason." That would be incredibly improbable. Clearly there must be a mechanism.
Fortunately, we have very good ideas about what that mechanism might be. There's increasingly strong evidence for retrocausality and/or non-locality, either of which provides a straightforward mechanism to produce those correlations. And, not surprisingly, either one of them would be very hard to reconcile with a non-deterministic universe.
