I just spent four hours, 15 minutes on the phone with Apple "tech support." My eyes are glazed, my brain is mush, my blood pressure is up. In short, this is not the time to write a post on anything but the pathetic, sorryass assistance provided to MacBook customers. Disconnected calls, had to start over; wrong departments and transferred calls; low-level tech supporters who knew not what they were talking about, I had to figure out two issues on my own; had to reinstall the entire operating system, wiped out saved information after being assured that would not be the case; wound up with a "senior" tech adviser who declared I would have to send this shitty laptop — which has had constant problems from Day One — off to repairs in another state FOUR TIMES before anyone would even consider replacing it, which I had already been told, by two other senior advisers, was an impossibility: "Apple does not replace lemon laptops, even while still under warranty — period." Nine-hundred dollars I spent on this MacAir; Apple has $1 trillion in the bank but won't shell out the replacement cost, perhaps no more than $450. I have been informed repeatedly that I'm just shit out of luck. All agree at Apple their corporate policy is insane, but also immovable, unchangeable, nonnegotiable. Beware.
