This is refreshing to know! I have been facing this blemish on my MacBook for 2 months already... and it's amazingly located exactly where BerryJuice's crack is. I actually saved the piece that has detached from the edge of the hand rest and almost considered super gluing it. But I didn't wanna downgrade it's appearance any lower. I was discouraged at first, but now relieved that I can repair this minor flaw on my MacBook. The little crevice of a crack on my MacBook has most likely collected some dust, dander, and my right hand's exfoliating dead skin cells. Kinda freaked me out. But, thanks for the vital information... (Yes, I am newbular on here). I hope the Apple Store can take care of this with no rebuttals.
