I can't speak for Amadeus, but Photoshop Elements 12 works quite well on my system currently running Mavericks 10.9.2.
Good to know. I've also checked at the Amadeus site and V2.1.3 is okay with Mavericks. I guess the various sites are slightly out-of-sync which, I suppose, is to be expected considering the vast number of software versions constantly being released.
