My Magsafe adapter for my Macbook has frayed and melted (it smells burnt too), and this is on my second adapter. The one that was packaged with my Macbook melted and frayed at the connection area, whilst this one has melted next to the AC adapter block. I checked the receipt and I bought it in March of 2007. I live in Sydney, so I was wondering whether the newly opened official Apple Store would still do a replacement? Has anyone else had this sort of problem, and has Apple helped? I really don't want to dish the $A109 price tag, though, it is slightly less than the $A125 of last time. Sigh. Pictures below.
