I'm amazed I remembered it !
PG would have to have some development going on in the background to future proof the applications wouldn't they ?
The Mac and Win both use all the same support files, it's just the audio files that are different, if they both used to same audio file format then you could have a crossplatform installer to install the content files, as a search will show these are available for software developers.
They repeat themselves doing all the Win content installers then have to then do the same for Mac, WHY ?
Kontakt uses crossplatform file sample format and a crossplatform installer.
Right now they can release the Win/Mac Plugin/Standalone at the same time if you have the crossplatform content installer using a common audio file format. The Plugin uses JUCE so this should be an obvious way to go.
All this should be like a No Brainer.
