  We construct a mapping of Bell and bipartite Leggett-Garg experiments for
microscopic qubits onto a gedanken experiment for macroscopic qubits based on
two macroscopically distinct coherent states. This provides an unusual
situation where the dichotomic measurements (and associated hidden variables)
involved in the Bell tests need only discriminate between two macroscopically
distinct states of a system i.e. correspond to coarse-grained measurements that
do not specify values to a level of precision of order $\sim\hbar$. Violations
of macro-realism and macroscopic local realism are predicted. We show how one
may obtain consistency with a weak form of macroscopic realism (wMR): that for
a system prepared in a superposition of macroscopically distinct pointer
eigenstates, the outcome of the coarse-grained pointer measurement $\hat{M}$ is
predetermined. Macroscopic realism does not however hold in a deterministic
fashion, where one assumes the predetermination of outcomes prior to the
unitary rotations that define the choice of measurement setting in the Bell
experiment. We illustrate an analogy with the Einstein-Podolsky-Rosen (EPR)
argument, showing how wMR can be regarded as inconsistent with the completeness
of quantum mechanics.
