Does this double the time tests take? I would consider mac compatibility issues to be relatively unimportant, maybe worth a weekly/monthly test.

No, they run in parallel. I agree the OSX tests aren't as important, but they do have some value -- for example, adding these tests here immediately revealed some deficiencies in a previous attempt to make bm3d an optional dependency.
