Hi Guys! After buying an iMac 1 year and half ago my GF started to like Mac OS X for it's stability and ease of use. She desperately needed a new laptop for her presentations at the company she works for so.. I convinced her to get a MacBook Pro this Saturday. (I know MBP updates are due but.. she needed it now) We get home, turn it on (it still had Tiger installed), upgraded to Leopard, installed Windows XP (for her occasional 3D modeling projects) and finally went back to OSX to install applications, setup time machine and etc etc.. This is where the problem begins! We transfered her Music folder from her former HP Laptop and when I tried to play a song via iTunes the left speaker played no sound at all! I went into the sound prefs pane and moved the slider all the way to the "Left" speaker and no sound came out of it. Of course that she is pretty much pissed of for buying a laptop from a high quality brand like Apple and having the bad luck of getting the MBP with this issue. My question is: Anyone have any suggestion on what I can do? Is the best option to just take the MBP to the store and get a replacement? Having to re-install everything that we had already installed so far will be a serious PITA. I'm sure you can relate, installing OS's is a time consuming activity. I know that there are no miracles, but some of you guys have dealt with these issues and who knows..? Maybe someone knows some easy solution BTW - I've already done all the Leopard and Firmware Updates and tested the sound in Win XP (it also doesn't play sound through the left speaker). And when using HeadPhones the sound plays in both so.. everything points to an hardware problem.
