Saturday night i noticed the crack on my white CoreDuo, week 29 build Macbook. I had been feeling a slight click when pulling my wrist off of the case after typing. I thought maybe the top case was coming slightly separated from the body for a few weeks, but then saw the crack. I dont know how long it has been there because its hard to see unless you pull it away from the rest of the top case. I immediatley called Apple Care since i bought the warranty. They told me that they couldnt take my word for it and that i needed to take it in to have it looked at or they would have to charge me. I hung up and discovered that the crack formed exactly where the magnet touches the case. On Sunday I took it to CompUSA since they have an ASC and he said that he had not seen one like that before, but that there was no abuse apparent on my behalf. He told me to call apple care back and explain that he thought it was a case in with Apple should fix. I called Apple Care back, they hassled me about the ASC not calling and making the report himself, but they sent me a box out, which i recieved in the mail today. I need to back up all my stuff just in case, but i plan to ship it off tomorrow in hopes of getting a new case. I have noticed that this problem only appears on the right side of the case. Does everyone else concur?
