It's a Mac. It works as I expected. Even an older Mac is better at most computing tasks than newer non-Mac computers. So my review is really about the refurbisher and their item description.This unit arrived with an unexpected screen scratch and a share partition on the hard disk. I wiped to HD and reinstalled the OS from Apple's website. Having owned Macs in the past I can say that a share partition is not usual. It was essentially a folder that was shared with an unknown person.The scratch doesn't affect screen performance but its bigger than I expected based on the description.Those are my only complaints after owning and using this refurbished Mac for about four or five months.
