Hello Guys! I am a newbie to these forums, so please cut me some slack. I have an early 2011 MacBook Pro 13" that is running OS X Mavericks....For the past few months (and this is before I installed mavericks), my battery is dying within 2 hours. I know for sure that is supposed to last longer than this. I also contacted the Apple Support and asked them about my problem...They brought me through some lengthy steps, but did not fix it.... Anyway, I was wondering WHAT DO I DO??? ..... Thanks for helping out guys!
