Work-around for Softwave Crash on Pairing
A friend let me try Wave some months ago and it worked awesomely. When I was setting up my own today, Softwave would crash every time I tried pairing my Wave, no matter how many system restarts or reinstallations of Softwave I did. I installed Wave for Work to see if my unit was defective or if it was a software issue (which I suspected) and as soon as it paired it prompt a firmware update. Once that was done, I was able to pair it with Softwave and another update came, to which now the unit pairs and works perfectly.
I don't know if this is a recurrent issue with Catalina users, but I hope it helps!
