New Mac has 3 battery cycles
Three cycles could be explained with
- One load cycle after the battery was manufactured (as part of the testing)
- One load cycle before the Mac leaves the factory (to make sure you can just boot it up when you get it)
- One you did yourself
but we have no easy way of knowing whether this is correct. Nevertheless I would probably only be worried if the cycle count of a new battery is higher than 10.
