Yeah I think pretty much all macs have a certain number of charge cycles out of the box for testing purposes, my made to order iMac had 5 charge cycles out of the box… so I think that’s normal.
But I am certainly convinced that Apple must refurb and resell returns as new… for example when I returned a brand new sealed iPad to an Apple store once, they actually removed the cellophane and inspected the device before issuing a refund… so basically they lost like 30% of the retail value of that brand new item by choice… I am almost certain that would have been resealed and sold as new…
Yeah Samsung does the same. It’s far to expensive otherwise.
