Stir the onion, applesauce, cranberries, apple rings, honey, cinnamon, apple cider vinegar, and 1 teaspoon salt together in a 6-quart slow cooker.
Sprinkle the pork chops on both sides with the remaining ½ teaspoon of salt, then nestle them into the slow cooker on top of the onion and dried fruit mixture.
Cover and cook on high until the pork is very tender, about 6-8 hours on low or 3-5 hours on high. The total amount of time will vary depending on the thickness of your pork chops.
When tender and cooked through, remove the pork chops from the slow cooker to a platter and skim or remove the fat from the surface of the sauce. Taste the sauce and stir in additional salt, pepper or apple cider vinegar to taste.
Serve the pork chops warm with the sauce on top or on the side and sprinkled with fresh thyme.
