Maybe you could get WinBB to look for Library OR LibraryM if you plug the drive back into Win you don't have to rename it each time ?

It's good it has the rename warning in the yellow flash message now.

Great job with the Mac version Peter !

I asked Joao to put the "Show User Library Folder in Finder" in his JBridgeM guide as the converted 64>32 plugs are saved there and BB has to see the folder to add them.
