Which one is from the simple image viewer applications on OSX would support full IPTC read support. I use Preview (standard in OSX) now but it does not display all IPTC fields even if entered by PM. The fields marked with a star in the IPTC info/stationery usually don't appear in most of the viewers. I understand these are extended fields not supported in the basic standard. But I would like to have any app to see them other than PM (it often helps my job to check something in an image out of PM then switch back to PM and continue work.
