I just bought a new MacBook Pro, and I asked the guy in the store, how best to transfer my files from my old MacBook to the new one, and he said FireWire, and he went and got me one. I bought it without even looking at it, as i presumed it was right. I've just got home now, and tried to plug it in to my MacBook Pro, just to discover it doesn't fit. I've obviously had to rip the packaging to get the cable out. It is described on the packaging as being a "Thin FireWire Cable, 6-pin to 6-pin". What wire do I need to transfer the files, and am I within my rights to ask for a refund, despite the fact the packaging is ripped?
