As mentioned.
It is stuck in Update mode. Does not show up in the Sysex dropdown menu. I tried to update firmware via Midi
but now it`s stuck in Update mode with GLIDE blinking.
I just did mine on a Macbook, running El Capitan, same issue. I finally figured out that it shows up in Midi Devices as “Minitaur” but in SysEx Lib simply as “In” …Selecting this port successfully updated the Minitaur.
