I am testing the latest and greatest (?) Mac OSX, High SierraThe latest version of VE Pro 6 opens just fine and loads my templates fine. However Logic Pro X 10.3.2 does not recognize the Vienna Ensemble Pro AU in the components folder.
EVERYTHING else: Kontakt, EW Play, Spectrasonics, Best Service Engine, UVI Workstation, U-he synths, UAD plug-ins and on and on are all already working under it just fine.
