Pretty much the same thing in our house. We have more or less given up on our Computrainer(s) except for use as "dumb" trainer used with a Stages crankarm power meter equipped bike.

It was very frustrating to go down to the basement to ride only to find that it was again no longer communicating with the computer (Apple iMacs primarily). The last time it truly worked was with Zwift and a Windows computer.

I had planned to see if I could revive the system using my new Windows computer this winter but then our household acquired a Peloton Plus.

Good luck.
