If you own a MacBook Pro with Retina Display and your battery stops taking a charge or starts malfunctioning in some other manner such that it needs to be replaced it could take five days or longer. A friend and colleague of mine in Austin, Texas, went to the Apple Store at the Barton Creek Mall to replace his battery and was told he would have to surrender his computer for five days while they replace it. Apparently the battery is glued in place. As a result, the bottom half of the computer has to be replaced when the battery is replaced. Really? Definitely a design flaw.
