Recently I updated my Mac desktop OS to Venture 13.5.2. That removed the Steinberg USB (which it usually does but can easiy be reinstalled). However, after installing the driver (Yamaha USB-MIDI V1.5.0), the DspMixFx application disappeared! And now when I look to install it again from the Apple app store, it seems to only be available for the iPhone of iPad. How can I get this app back on my Mac desktop?
