I have once again come here to vent my frustration and ask for advice! Some of you may have read my post here: http://forums.macrumors.com/showthread.php?t=1727196 I have a 2011 MacBook Pro who's graphics card went bad. Apple fixed it while messing up several complements. After my second trip they replaced the logic board, screen, and unibody. Yay! Yesterday, my computer froze and forced me to force shut it down. I can no longer boot from my account, recovery partition, mavericks USB, or the SL disk that came with it! I get a dark blue screen with black lines. I have an appointment with the Genius Bar and one more month of AppleCare but I'm so upset. This will be the third repair and I asked the man last time "since you are replacing a faulty part with an identical part how do I know it won't happen again?" He just shrugged. Part of me wants to demand a new MacBook Pro, but I know that will be pointless. I put $2500 into this machine when I bought it and I have no trust in their repairs. Should I talk to a manager? I'm just so upset and was wondering what any of you thought. I'm a student who NEEDS a computer.
