Hello Robert,
I just had a talk with my colegue in charge of the compatibility of the products. He confirmed me the problem was that on the macintels and ONLY macintels it wasn't possible to use plugins VST <2.3 (it was a nice little surprise from steinberg) ; So the prophet V and AF can't work on this platform for the moment..(sorry)
Anyway, an update for the Prophet V should be available soon, and for Analog Factory a bit later...
