You will get it going it is just some minor thing you missed as in the last post.
The Win version you can just add a folder to the Drums folder with the files in, rebuild and it finds it but you can't do that with the Mac, you have to edit the txt files.
If you tick the "Show RealDrums that are N/A" and it will show the one you added to the PGALLDrumFolderNames.txt in the list, so BB searches for the corresponding drum folder to what is in the list to what is available.
