Upgrading my daughter’s laptop , system menu say recommended batteries change. It works even on batteries not just as long as when it was new . Other than the battery recommendation, I don’t see any issue. It is working great would be a perfect laptop for day-to-day tasks as well as photo and video editing. Legendary Apple quality , light and easy to take around. Laptop only, no charger (as the new one comes without a charger, I keep this one , lets save the planet and put more lonely in Apple pocket ;) ) you just need a 45 or 65w usb c charger plenty on amazon for cheap anker or ugreen are good !
