Up to a point. If there is a technical issue the inevitable result, at the genius bar at least, is to reimage the Mac every time without attempting to diagnose the problem.
It's like doing a heart transplant without working out what is wrong with the heart.
Inevitably the chain of events that caused the issue to occur will happen again and nothing ever ends up ultimately resolved.
Case in point: recently someone came to me as a last resort after refusing the genius bar "wipe the machine" solution. The problem was a runaway process in an HP provided print driver (pdf2pdf) due to a bug. The outcome was to flatten the machine and start again. When the user got home, they were to be told to install the HP driver software again from the CD with their printer. Now that would just cause it to happen again straight away.
My solution:
1. Actually bother to use Activity Monitor to work out what is going on (beyond the average Genius Bar staffer).
2. Google it (also beyond the average Genius Bar staffer).
3. kill the process, install updated driver. Duh.
It makes me wonder how many people have been screwed. You've just been bought off with free kit because they can't make a lasting product [1]
[1] MBP logic board failures are very common, as are earpods. I'm on my 3rd logic board for an MBP and around the family, the 9th (!) set of replacement earphones. Whereas my Lenovo T61 and Sennheiser earphones are both 6 years old with no problems...
