Hi, Grant

Thanks very much for your message.I’m sorry,there is no USB driver for New Mac OS by now.The UFv1 are discontinued and new drivers are not being issued. I can understand your reaction to this. I have had the same experience when up-grading to a new OS and finding that some software and hardware will not work on the new system.
However there is a solution for you. Although there are no drivers,you can overcome this by connecting your UF7 to your PC with USB MIDI Interface to let them work again.Or if your sound card has midi port,it’s ok,too.
