Trim chops of fat. Sprinkle generously with salt and pepper on both sides. Heat a large cast iron skillet over high heat and then swirl in olive oil. Lay in chops and don't move them for a few minutes to assure a good golden sear forms. Turn and brown well on the other side for a total of about 10 minutes. Remove chops to a warm plate.
Swirl butter into pan. Add onion and apples. Saute til onion slices are lightly caramelized and apples have begun to soften, about 8 minutes. Stir in beer or other liquid. Return chops to pan
Cook til pork is tender, about 15 more minutes, depending on size of the chops, turning halfway through and covering chops with apple mixture. If the mixture needs a little thickening, remove chops to warm plate again and simmer mixture on high for a few minutes to reduce. Serve chops over rice or mashed potatoes with a large spoonful of the apple onion mixture over the top.
