I'm transferring files from my old Aperture library on my old iMac, to a new library on my new iMac. Same version of Aperture. Should be no problems. Except, Aperture on my new iMac is a bit choosy about which files it will read.
I've imported images in batches, establishing a nice new library structure as I go. The export of images from the old Mac to a usb drive goes without any problems, but when I then import into my new Mac, every now & then a photo gets tagged as being an 'unsupported image format'. Quite how it can be unsupported by Aperture, when Aperture processed the damned thing in the first place, is beyond me.
Any solutions/suggestions?
