I was kinda afraid of buying a refurbished apple product but I haven't had any let downs like any of the other reviews. I had trouble setting up but that mostly due to learning how to negative apple systems. The computer itself needed a little cleaning had what seem to be some type of glue on it. Has a little tiny scratch mark on it but I don't mind. Once I got it all set up, it let me update to the latest version of Mac Os. It runs smoothly. It's the best computer I've had for this price. I'm very pleased with my purchase. I've always wanted an apple computer but just could never afford it.. Now I can say I finally got one.
