Lets say I a go my faulty mbp to the service, while I have 'apple care' coverage.
And they say that the solution they suggest is giving me a whole brand new mbp.
Questions:
- Will it be a mbp of the same or better specs? Will it be the corresponding current model?
- Can I ask them to make a 'migration' of my previous osx system to the new machine, if the hard disk is ok? Will they do it? When the mbp crashed, I had a backup but not the most recent.
- 'Apple care' package will continue its (remaining) coverage, with the new machine, until it expires?
- Do I have to make any new action about it, registration etc?
First and foremost, Apple will never look at your faulty Mac of any kind and then get you a whole new one. Even if they did make their policies with Macs similar to their policies on iPads, iPods, Apple TVs, and (in some cases) iPhones, they wouldn't get you a whole new one; they'd get you a refurbished version of exactly what you had. Again, they're not going to switch to that kind of policy anytime soon, so your questions are essentially moot.
They will, at worst, mail in any MacBook (Air, White, Black, Pro, or otherwise) to the depot where they will completely refurbish it at either a flat rate (if you are out of warranty) or at no charge (if you are in warranty), replacing as many components as they feel are necessary for the repair of your MacBook. They do not offer this service for iMacs, Mac Pros, or Mac minis of any kind or generation. Otherwise, you're looking at a per-part replacement.
If you have repeat repair issues that don't go away after three component replacements of the same components (i.e. heating issues, graphics/cpu/logic board issues, then you can call to Apple's Customer Service department and ask to have your machine swapped out with the current day equivalent (i.e. if you have a Black MacBook having recurring issues that you keep taking it to be repaired for and you are still covered in your 90-day warranty each time, they'd likely swap it for a 13-inch retina MacBook Pro as that is the modern day equivalent). But they will likely want to do some sort of tests to make sure that they cannot repair it consistently, but typically, they'll bend over backwards, take your old machine and foot the bill for a brand new one.
