I purchased this MacBook Air after several issues with Amazon and other laptops.  It arrived quickly but worked for only one day.  Tons of error notifications and indicated an update was needed to a completely new IOS and is about 6 updates behind .  It never turned on again. I would think the seller would refurb and update to work in current time before shipping.Save your money and the hassleStill haven’t heard back from seller and only option is a refund that takes 5-7 days after they receive it back (despite my data being on the machine and the delete via Apple is throwing an error code).9/8 update: seller has responded.  Asked for photos of a cosmetically perfect laptop to “send to their quality team” when they were told numerous times that it was a software issue.  Escalated to Amazon several times and reported seller.  Really cautioning against buying from them. I’ve had a laptop I couldn’t use for almost 2 weeks while they’ve held my money.
