put it in your Drums folder then click rebuild in the drum picker, I think they fixed the Mac so it's the same as Win with ExtraDrumFolderNames.txt
"This file has list of UserDrums not found in PG's list of RealDrums"
if not you may have to add it to Applications/Band-in-a-Box/Data/PGALLDrumFolderNames.txt
