 It is to be noted that the indeterminism of modal quantum mechanics does not imply that the present quantum state of a system fails to determine its future quantum states. The Schrödinger equation is deterministic, and the probabilities encoded in the quantum state therefore evolve in a deterministic way. Indeterminism comes in when we consider the actual values of observables, which are not predetermined even if the quantum state is completely fixed: modal interpretations take processes of actualization to be essentially probabilistic.
