Aperture raw update
Going back to some old folders and albums in Aperture, I noticed an advice at the top of the adjustment tab telling me that the RAW Apple engine for the selected pictures had been updated and to click on the box to reprocess the shot; doing so, nothing happens and I can't alter anything for that picture. Anyone have an idea of what's going on and how to fix that ?
