Purchased brand new (not open box) silver Macbook 512 on 03/20/16. Unit did not work properly and would not allow me to log into my Apple ID. I called Apple support, they recommended returning it to Best Buy. Returned on 03/22/16 They exchanged it for another supposed brand new Macbook (box was sealed as far as I could tell) When fired it up, I was immediately suspicious as it has Yosemite as the OS, and also still has some Apple ID issues logging in. Contacted Apple support Apple says the unit was purchased before on 9/13/15. Warranty coverage that Apple will not change..... Limited warranty 2016-09-13 (172 Days Left) No phone support Expired 103 days ago Serial Number: C02Q60U3FWW4 I cry foul........I don't care if I got $300 off or not on their "sale".........it's supposed to be a brand new machine! Not an open box or already sold unit. Needless to say it's going back immediately. I should of known better than to purchase Apple products other than at an Apple store. Best Buy is not being at all honest with customers... I'm done with them.
