One: What is the best way to clean the top case? The sticker that seals the cloth pouch it came that says to read the EULA yadda yadda yadda had a big chunk that came off and got stuck right to the top of the Macbook, and I'm not really having any luck peeling it off, because it's designed to be fragile, I guess, to avoid tampering or something. Second, is the fan supposed to sound like a dog whistle? The fan is so high-pitched, my ears are bleeding. Figuratively.
