I've never been able to download nor upload any configuration to/from my Pronto 990 (European version of the US 7500) with Parallels Desktop, the Pronto seems to be well recognized when connected (boeioong sound of USB ...) but when I click "upload" I get a message : "The connected device is not supported by ProntoProEdit NG" !

The only solution that work seamlessly with a Macintel is to install Bootcamp : then your Macintel behaves as a true PC, but you must reboot to commute to Windows … contrarly to Parallels. I use it without any problem with ProntoProEdit.

Any other experiences on are welcomed !
