Since `macDefaultOrderArr` is already mac-specific, I'm not sure how much this helps without also refactoring the rest of the logic.

One possibility would be to move the if-then-else block up (before the check for the `"prism.order"` system property) and then assign the default pipeline after the tryOrder is assigned. I'll leave it up to Jay as whether he wants to do this.
