  For a bornology $\mathcal B$ on a cardinal $\kappa$, we prove that the
$\mathcal B$-macrocube is normal if and only if $\mathcal B$ has a linearly
ordered base. As a corollary, we get that the hyperballean of bounded subsets
of an ultradiscrete ballean is not normal. These answer Question 1 from
\cite{b2} and Question 14.4 from \cite{b1}.
