Apple forums openly talk about problems in their products and fixes.
Apple is well-known to bury data. The piece of data I personally noticed regarded data corruption in Rev.1 B&W G3 macs. They had an article in the TIL which told you to buy an ATA card or FWB toolkit and slow down your drives. When they folded the TIL into the KB they pulled in articles before and after it, but they dropped this one. They lie, cheat, and deceive; that's what they do.
