Works perfectly except this has the “butterfly” keyboard and at the moment the “R” key is recognized intermittently. Could just need to be blown out with compressed air (these keyboards are really susceptible to dust). I'm not using this machine anymore and it's time to pass it along to a new home; if you can get the keyboard to work great, otherwise, consider this a “parts” machine? Included is the laptop itself (which has a few tiny flaws; I'd call it an A- or B+ in cosmetic condition), the original box and packing materials, and the OEM 29W charger and USB-C charging cable. (The external keyboard, headset, laptop stand, bicycle, Labrador, etc., are not included.) Smoke free home (but obviously not pet-free). This was my main portable workstation over the summer but I've since switched to Apple Silicon. This machine is fully supported by Apple on Big Sur and I've installed it with a fresh copy of that operating system using Apple's Restore functionality. It will also run Monterey or Ventura via OCLP if you're so inclined. The battery is about what you'd expect for an 8 year old machine; has about 73% of its design capacity left after 284 cycles (see screen shots).
