Model A1466. This was my wife's personal laptop since new. Overall very good condition. Minor aluminum shell scratches and faint sticker residue. Slight dent in corner does not affect screen or performance. No problems with screen, keyboard or touchpad. All ports work. Battery life is OK. Latest Monterey installed, Apple does not allow upgrading older models to new OS. Genuine 45W MagSafe 2 power supply included PA-1450-8. Tech specs at https://support.apple.com/en-us/111924. Apple hardware diagnostics passes 100%. Clean install, unlocked, no Apple ID. Thanks for looking.
