The French importer of the RME Fireface informs us that the Mac driver for its inteface won't be available in Europe before early October...here goes the whole answer by Arbiter :

"Concerning the Mac drivers, RME said : not before early October. By the way I have been told off by the manufacturer because they said I annoy them about this driver every day. Sorry for the delay, we have written new ads at every single retailer's to warn the customers that this driver is not available yet. You need to know that unsatisfied customers can be refunded if they bring their full package back to their vendor."
