In the MIDI Audio Devices things look marginally better as it gives me a number of popup menus, but there also things don't work too well (at all, in fact). Unfortunately, after plugging in the Lambda into the Mac Mini I get a 'The Selected device has no outputs/Inputs' notice.

The Lambda works (barely) on my windows 10 machine, but now that I have a working Mac, I was planning to use my iPad and my newly back from the dead Mac Mini as a sketchpad for my songwriting. I was a lot less thrilled when I plugged in my Lexicon Lambda Studio SoundCard. The SSD alone speeds up things dramatically and I am looking to upgrade the RAM (currently 3GB for some reason). it went from essentially a high tech paperweight to a pretty useful machine in less than an hour. I have just revived an old 2009 Mac Mini (3,1) with High Sierra.
