Ok I will try and remember,
Make sure you rename the Library folder in the Realtracks folder to LibraryM so your holds still work.
I'm using the AudioPhile version that uses wav files it works fine with MACBAIB,
you can use FormatFactory (untick Ask Toolbar or cancel out during install) if you have just got the wma files,
choose Audio M4A click Add Folder (RealTracks, Drums) > tick Entire Tree > Filter *.wma
and set it to Output to Source File Folder (make sure you have enough space). Not sure if FF did them all in one go or if I had to run a few instances of it or I just encoded the Accordion folders first then Banjo and so on? You can use FastCopy to copy the folders and filter out *.wma .
I thinks I moved the Styles Folders and the styles and other files in the root dir into Styles Folder in Mac and all the XT2 ST2 into the Soloist Folder in Mac ? but I have a copy in the Styles Folder also, if someone with the proper Mac install can have a look and check.
EDIT: make sure you select Default "0" for Audio Channel in FormatFactory Output Settings, this will convert the file to mono if mono, stereo if stereo.
