Apple MacBook Pro 15-Inch Retina Late 2013 Core i7 2.3GHz 16GB RAM 500GB SSD, with Big Sur version 11.7.4. The laptop needs some parts replaced in order to work properly. The screen has a crack across it which makes it difficult to view, also the mousepad does not respond. I included an Apple mouse to work with it. Also included is the charger, it is broken, put tape on it, still charge with no issues but it is as it is! If the laptop gets the screen replaced and the mouse pad fixed, the laptop works perfectly, battery holds a normal charge, and all is verified to work.
