My Macbook charger is falling apart. its still charging my computer but as soon as I disconnect it from the wall the whole thing just falls apart and I have 3 different parts in my hand. also sparks come out. which is obviously not a good sign. I no longer have the warranty...its been just a few months over a year since I got it... I hate that the chargers are so expensive! and made so poorly.... I thought apple would have improved those by now. any ideas on where I can get a charger for cheaper than the apple store? or a way to get apple to realize its a manufacture defect....I didnt yank it out of the wall or anything!
