I’ve been unable to reproduce this failure so far, even on the same version of Matlab. The only difference is my OS is still High Sierra 10.13.6.
Would you mind downloading yet another version of t_most_w_ds.m from the same URL <https://raw.githubusercontent.com/MATPOWER/most/master/lib/t/t_most_w_ds.m>, then run ... t_most_w_ds(0, 'DEFAULT', 2) … and send the result? This should run t_most_w_ds exactly as is run when you type test_most, but with verbose output so I can see what’s going on. Thanks for helping to debug these test failures.
