We give the first examples of derived equivalences between varieties defined over non-closed fields where one has a rational point and the other does not. We begin with torsors over Jacobians of curves over and, and conclude with a pair of hyperkähler 4-folds over. The latter is independently interesting as a new example of a transcendental Brauer-Manin obstruction to the Hasse principle. The source code for the various computations is supplied as supplementary material with the online version of this article.
