Pat chops dry and season with salt and pepper. Heat oil in a large skillet over medium-high heat and sear chops for 4 to 6 minutes per side until browned and at least 145°F in the thickest flesh; transfer to a plate.
Reduce heat to medium, add butter and apples and cook for 5 to 6 minutes, turning gently, until the wedges soften with browned edges.
Whisk cider, mustard, vinegar and thyme and pour into the skillet. Simmer for 2 to 3 minutes until lightly reduced.
Return chops and their juices to the skillet and warm over low heat for 1 minute without boiling hard.
Serve after the pork has rested for at least 3 minutes total, with apple wedges and a small spoonful of cider sauce alongside.
