MacBook, I just got it from my brother and I don't know how to use it, honestly. There's a crack on the edge of the screen as shown in the picture, and it's working fine. The battery gives me 99% power, but when I unplug it from the charger, it turns off. It's not working, there's no problem with it. These are its specifications. Whoever knows about it, I honestly don't know about it, I didn't like it. Location: East Riyadh
