The good news is that my Mac Book Pro saga came to a happy end.
In the last episode Omer and Oren, my colleagues went to the Apple store in Burlingame (CA) to hand the computer for returning repair.
Again, they had to prove that something was broken, luckily for me, the Genius turned to the store manager who decided to take the faulty mac and get me a new one instead.
Just before total frustration, a person with good instincts for customer service, made the right judgment call! I wish this could have been done sooner, but at least I’m back working on my Mac!
