RAM is 8 GB 1600 MHz DDR3 Fully working but only when plugged into power source - it has a battery issue. Note that this MacBook's charger does not charge this laptop and it is sold with this charger:• Output: 14.85V ⎓ 3.05A• Power: ~45W The battery would need replacing as the laptop only works when it is plugged in. Otherwise, the laptop condition is good - the general appearance is good, little wear and tear, some marks on the screen which I’ve tried to capture in the photos however when turned on these cannot be seen.
