Great shape, runs well, everything is working. Tested audio/video by successfully connecting to a Zoom meeting before wiping the drive. Currently has Catalina installed, as this was what I had available to wipe the system clean. You will be able to upgrade as far as Monterey for free once you are logged in.
See system profiler screenshots for details on battery health etc. I will throw in a brand new (third party, highly rated) charger so you have one. (Original Apple charger shows extensive cable yellowing from overheating, as this generation tends to, so I am not comfortable giving it to anyone. Send me a note if you really want the Apple charger instead though.)
