Hi, I will be moving to the carribeans in a few months, St-Vincent to be precise, and I am bringing my iMac (8.1). I know the iMac is auto switching, but what I cannot find is where to buy the appropriate power cord. I went to the local apple store and they told me that they don't sell power cords, which I find suspicious. Actually they also told me that the iMac wasn't auto-switching. Could someone point me in the right direction? As a slightly off topic question, I am considering a MBP when/if the refresh takes place, would I have to replace the entire magsafe or simply the lead that plugs into the wall outlet? Thanks!
