This is probably the first review I've ever written and it sucks that it has to be a 0-star review. At first, the Mac seemed fine and worked great. When I came back from work a few hours later, it gave me multiple errors whenever I tried to open up Safari. Apple support then told me to try to update it. The Mac then told me there was an error trying to update. This happened several times before I decided to reset the Mac. Now I can't even use it because it's stuck in a loop saying "Enter a password to unlock the disk Macintosh HD". No matter what I put in, it loops back to it. I'm returning this item as soon as I can and recommend that if you buy a laptop, buy it new instead of used. It's not worth the time and effort.
