Combine the maple syrup, balsamic vinegar, olive oil, garlic, rosemary, salt, and pepper in a medium saucepan, and whisk until the salt dissolves.
Place the pork chops in the marinade and allow them to sit at room temperature for 30 minutes.
Brush the air fryer basket with cooking oil, remove the pork chops from the marinade, and place them into the air fryer basket.
Air fry at 400 F for 10 minutes, flipping halfway through. Internal temperature should be 145 F in the center of the meat.
While the pork chops are cooking, place the saucepan with marinade on the stove over medium heat and simmer for 10 to 15 minutes, or until reduced by about half.
Allow the pork chops to rest for 5 minutes, then slice, and serve with sauce.
