I was able to successfully pair my Morph with my Macbook Pro running the latest OS. However, the MIDI device does not appear in MIDI Monitor or my software. Am I missing something?

Yes, there is an extra step for Max OS. Open Audio MIDI setup, go to MIDI Studio, and under the MIDI Studio menu, select “Open Bluetooth Configuration.” There, you can make sure that Bluetooth MIDI is enabled for the Morph
