Can anyone enlighten me on which particular Filezilla version I need (on Mac)

how it is used as a conduit between Rapidweaver and Yahoo.
In case you mean direct server-to-server transfers, that's not supported by FileZilla, yet.To connect to an FTPS server in FileZilla, set the correct Encryption (Site Manager), or use ftpes:// (Explicit) or ftps:// (Implicit) as hostname prefix.
