Ham and Mac Bake

I got this recipe from a casserole cookbook I checked out at the library. I was very intrigued by the apples in this. My kids weren't sure but they ate it and DH and I enjoyed it very much. This is NOT your ordinary mac and cheese, but good all the same. EDITED: As per the review, I've rechecked the recipe at our library and I indeed had a typo and have changed this.
