    just took delievery of my sexy beast of a new machine.

    i love it to pieces, apart from the above issue.

    so far, i've tried in DVD player, where it only comes from the left and in logic.

    in logic, when i panned everything to the right, nothing. as though that speaker wasn't connected.

    i don't plan on these speakers being my main ones, but if this expensive box has a problem like that it should be fixed.

    thanks for any help

    something as big and obvious like that should absolutely be taken back. Plus you can prove it to them. I have a problem that is impossible for me to show them at the store. I can show pictures i guess.

    Have you looked in the Sound tab in System Preferences?

    Click Output and see where the Balance slider is, should be in the middle.

    Simple, but worth checking before you throw it back at Apple.

    hahaa, the sound preferences thing was the first stop. if i hadn't have tried that i shouldn't be on my music tech degree!

    it has been fixed now, by Apple, over the phone.

    in case you are wondering out of interest.

    i had to take out the battery and put in back in.

    then hold down OPTION+CMD+R, then press power, then hold down P in addition (so that's four keys pressed). while i was holding these keys it made the load sound, then rebooted, made the sound again.. ..

    once you have three sounds, it's performed a hardware reset. might be useful having a go if your display etc isn't working.

    i just let it load and it worked fine!

    In essence you performed the following:

    SMC reset - remove power and battery, press power button, wait 5 seconds and then insert the battery...

    and a PRAM reset - the four keys you mentioned.
