ok i posted this on the apple discussion forum, but thought I would post here as well. So i got a new MBP, and when I transferred my A3 library over, I noticed that ALL my .TIFF (they are the 1Ds RAW files, before .CR2 was around) have been resized. On my old MBP, they would be full size, and Preview would open them up correctly. Now even Preview resizes them. I open up the files in PS CS4 and ACR opens up, so I know the files are not corrupt or anything. All my .CR2 files are all fine, and are full size when in A3. **EDIT** now all my TIFF files are corrupt when viewing in A3. here are some screen shots. WTF?
