This is an M1 based Macbook Air. I installed the version of software you sent and it crashes on exit. Luis in support recommended I download and install the version from 5/25/21 - I was able to update the controller firmware and load the show!!
Thank you so so very much for your help!
For the reference of the masses:
MAC OS Monterey ver 12.0.1
ADJ My DMX 2.1 ver 1.12.12-2710
