I’ve just got a new MyBook Studio Edition II and installed WD Drive Manager (2.2.6) on OSX Lion and it works fine.
The only strange thing I experienced was that once I installed the 64-bit TURBO+ drivers then WD Drive Manager stopped recognising my drive (I could still access the actual drive fine for file access/copying, but couldn’t see/manage it in WD Drive Manager).
Anyway I did some file transfer speed tests and the TURBO+ drivers seem to be a waste of time anyway so I uninstalled them rebooted and WD Drive Manager is happy again…
